    DNA Replication :

    Dna Structure :

    Using PCR, copies of DNA sequences are exponentially amplified to generate thousands to millions of more copies of that particular DNA segment. PCR is now a common and often indispensable technique used in medical laboratory and clinical laboratory research for a broad variety of applications including biomedical research and criminal forensics. PCR was developed by Kary Mullis in 1983 while he was an employee of the Cetus Corporation. He was awarded the Nobel Prize in Chemistry in 1993 (along with Michael Smith) for his work in developing the method.

    Typically, PCR consists of a series of 20–40 repeated temperature changes, called thermal cycles, with each cycle commonly consisting of two or three discrete temperature steps. The cycling is often preceded by a single temperature step at a very high temperature (90 °C (194 °F), and followed by one hold at the end for final product extension or brief storage. The temperatures used and the length of time they are applied in each cycle depend on a variety of parameters, including the enzyme used for DNA synthesis, the concentration of bivalent ions and dNTPs in the reaction, and the melting temperature (Tm) of the primers.

  • Multiplex qPCR: Criteria for Success

    1:9:12

    Current best practices for gene expression analysis by qPCR recommend the use of multiple normalizers and, potentially, a second gene of interest (GOI) assay. For samples with limited nucleic acid content, such an experiment may only be achieved by performing multiplexed qPCR assays. Even when working with abundant nucleic acids, multiplexing can save time and money. Achieving successful multiplex assays depends upon several criteria, including using robust assays, correct reagent and target concentrations, and appropriate cycling parameters. Using data from several assays, we demonstrate how PrimeTime® qPCR Assays simplify a 4-plex assay system, and discuss factors that influence the success of using these assays in a multiplex format. We also compare the use of master mixes assembled de novo to commercially available reagents and discuss their effects on multiplex assays.

  • What is Ion AmpliSeq Chemistry? - Seq It Out #6

    4:48

    “What is Ion AmpliSeq™ Chemistry & how does it work?” Let’s find out what this new technology can do for you.

    Next Generation Sequencing is now producing more sequence, faster than anyone had ever envisioned just 10 years ago making it now possible to sequence a genome in days rather than months or years.
    However, for many applications this large amount of data becomes overkill, creating processing and informatics headaches, and adds additional cost with little to no benefit.
    Rather, for many of the more standard questions being asked in the lab, a focused approach, or targeted sequencing method, that zeroes in on specific genomic regions of interest, can result in significant savings in terms of time, effort, and money. And, perhaps most importantly, can speed up getting to that answer you’re looking for. So what is targeted sequencing and how does Ion AmpliSeq™ chemistry fit into the picture? , Simply put, using current genomic knowledge, a targeted sequencing approach introduces a sequence enrichment step focusing in on genes or even genetic variants of interest - A good example might be the targeting of oncogenes and tumor suppressors in a cancer research study.
    Early approaches, using hybridization based techniques, enabled specific regions to be pulled out of the genome. However, these methods were limited in their specificity resulting in representation of regions of no interest. Additionally, relatively large amounts of starting genomic DNA were required for these traditional hyb methods. Leveraging over ten years in PCR assay design and preamplification methods developed by our Applied Biosystems colleagues, Ion AmpliSeq™ targeted enrichment offers a vast improvement over these early approaches delivering a unique, highly multiplexed PCR based workflow with clear specificity and uniformity benefits. Additionally, extremely low DNA input amounts can be amplified through the PCR process, as low as 10 ng.
    So what is the Ion AmpliSeq™ approach, how does it work, and what makes it so remarkable?

    Let’s take a look at our lab book

    At its most basic level, an Ion AmpliSeq™ panel consists of a pool of oligonucleotide primer pairs, each pair designed to amplify a specified genomic region. Unique to this approach is the ability to multiplex up to 24,000 primer pairs in a single PCR reaction!

    Following simple PCR amplification of the selected genomic regions, remaining primers are digested and a library containing the remaining amplicons is prepared for sequencing.

    It is worth mentioning two key implications to how the design of an Ion AmpliSeq™ Panel is approached.

    First, a panel can be designed to interrogate all bases across a gene or can be focused on specific mutation hotspots.

    Since a gene design relies on the tiling of overlapping amplicons across the sequence of interest, the consequence is that overlapping primer pairs must be separated into independent PCR reactions. As a result, this approach will require two separate PCR multiplexed reactions per sample to achieve full coverage.

    In contrast, a mutation hotspot design typically results in non-overlapping amplicons whose primers can be accommodated in a single multiplexed reaction.

    Lastly, consideration of the sample source is important to final design performance. Shorter amplicons with a maximum length of 175bp work best with degraded sample sources such as FFPE but come with a trade-off of coverage within the design.

    Now you may be thinking “this all very interesting but I still don’t know how to create a design”? Never fear, Ion Torrent offers a variety of predesigned panels designed with input from the experts in the field, and if none of these panels meet your needs, custom design is made super easy using our online AmpliSeq Designer tool. Now that you know a little bit about what Ion AmpliSeq™ targeted sequencing has to offer and how it works, feel free to play with our design tool – after all it is completely free to try.

    I hope this video was helpful on explaning the Ion AmpliSeq™ Chemistry, and I am sure you’ll have more questions.

  • Highly efficient genome editing and cell engineering in stem cells using CRISPR/Cas9

    57:05

    Advances in genome editing has empowered researchers with highly efficient and versatile gene editing tools like Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) system thereby making it relatively easier to target user defined endogenous genes in a sequence specific manner. Stem cells have been a preferred platform for various applications including gene function analysis, drug screening disease modeling, and tissue engineering. Therefore novel tools that enable rapid and precise gene manipulation in stem cells are required. Presented here are CRISPR/Cas9 tools and workflows that allow accurate design and rapid synthesis of gRNA along with delivery of Cas9 protein/gRNA RNP complexes into a variety of cells through optimized transfection reagents or electroporation. Discussed here are the results from different CRISPR/Cas9 formats tested in stem cells. Using these formats we have edited mouse embryonic stem cells (ESCs) and human iPSCs with up to 80% to 60% genomic cleavage efficiencies, respectively. The methods described here facilitate efficient disease model generation thereby accelerating research in the field of gene therapy and regenerative medicine.

  • VariantPro™ Targeted Sequencing Technology

    9:57

    LC Sciences offers a customized solution to high-throughput genome wide variant analysis. The VariantPro™ system is comprised of three distinct innovations, all developed by scientists right here at LC Sciences: Relay-PCR™, Omega Primers™ and OligoMix®.

    Relay-PCR™

    Relay-PCR™ is a new, simple, and robust method of multiplexing PCR. A single PCR run accomplishes two functionally separate reaction phases without any primer removal step, resulting in a significantly simplified, one step workflow. A single pair of common primers and a mixture of multiple pairs of specific primers are added to a genomic DNA sample in a single tube. Both a selection phase, where the genomic targets of interest are captured, and a library amplification phase, will occur during this single PCR reaction.

    Omega Primers™

    An Omega Primer™ may exist in various forms, but all are composed of three functional segments. This segmented design provides several desirable features and/or properties in various applications.

    Generally, the 5p arm acts as the anchor to bind the primer to a DNA template. The 3p arm checks sequence specificity before polymerase extension is initiated. The loop provides a separation between the two arms, and may serve additional purposes. Omega Primers™ are well suited for multiplex PCR applications where the flexibility to design highly multiplexed primers to target many regions may be limited due to PCR thermodynamics.

    OligoMix®

    Taking advantage of VariantPro™’s high multiplexing capability, custom designed targeted sequencing projects may require very large numbers of custom oligo primers, up to tens of thousands. OligoMix® is an established, proven method of massive parallel oligo synthesis that quickly and cost effectively provides the required oligos. Thousands of custom oligo sequences are synthesized at once on a microchip and then cleaved, releasing them into solution in a single microtube ready for use. OligoMix® has been demonstrated as an effective method of oligo synthesis for several targeted sequencing methods including: Molecular Inversion Probes, Selective Genomic Circularization, Oligo-Selective Sequencing and VariantPro™ targeted sequencing.

  • DNA Extraction from Plant Cells Practical Experiment

    6:14

    This video shows how to extract DNA from plant leaves using commonly available kitchen ingredients.
    Do check out my other genetics related experiments by clicking on #GeneticsLab #ThomasTKtungnung above the video title.

    DNA is one of the genetic materials of most living organisms including plants , animals, bacteria, fungi and viruses. It is the hereditary material responsible for the passing on of characters of the parents to their offsprings through generations. Information is stored within the DNA molecule in the form of genes which are made up of several codons formed by the 4 nitrogen bases Thymine, Adenine, Cytosine and Guanine in different combinations. Each codon is made up of a combination of any 3 of these 4 bases and are called triplet codons. These triplet codons are transcribed into the complementary mRNA which is then transalted into the corresponding amino acids encoded by the triplet codons. These translated amino acids eventually form proteins, enzymes and other biomolecules that drive the various physiological functions within the organism.
    Extraction and isolation of this important molecule is the first step in any experiment on Genetic engineering or Recombinant DNA technology.
    In biotechnology research, Extraction of DNA is carried out using expensive enzymes and and chemicals under controlled conditions in a lab setting.
    One can also extract and isolate DNA using cheap and easily available materials that one can find in any household. Although it’s a rudimentary alternative to the method employed in the laboratory, the basic principle remains the same. The material is crushed to separate the cells. The cell wall and cell membrane of the cells are then destroyed to reveal the DNA which is then extrated into a form that’s visible to the naked eyes.
    In this video, we try to extract and isolate DNA from a plant material such as leaves, using materials that you can find in your kitchen.
    To perform DNA extraction from plant cells, you’ll need the following:
    Blender or Pestle and Mortar
    Weighing scale
    Strainer or a funnel with filter paper
    250ml beaker or cup
    Ice cold water
    Table spoon or spatula
    Test tube or a small graduated cyliner

    Meat tenderizer or Ice cold freshly prepared Pineapple juice or Papaya juice (both are enzyme sources):
    Ice cold Ethanol or Isopropanol (Rubbing alcohol):

    To begin the experiment, weigh 50-100 grams of the plant material.
    Transfer it into a pestle and mortar or a blender and blend it with about 100ml of ice cold water and half a teaspoon of Common salt.

    Filter the blended mixture into a beaker using a strainer or a funnel with a filter paper cone.
    Add a tablespoon of detergent powder, dishwahing liquid soap or SDS to the filtrate in the beaker and stir the mixture gently.
    Allow the mixture to stand for 5-10minutes.
    After 10mins or so, transfer about 10ml of the mixture in the beaker into a test tube or graduated cylinder.
    Add a pinch of meat tenderizer or about 5ml of pineapple or papaya juice to it. Gently agitate the test tube to mix the two liquids.
    Wait for 5-10mins for the digestion reaction to occur.
    Now, hold the test tube in an inclined position and using a glass rod or a pipette, carefully add about 5ml of ice cold rubbing alcohol or ethanol such that the alcohol flows gently down the inner wall of the tube and forms a layer on top of the digested plant extract in the tube.
    Observe the interface between the two liquids. You will find the DNA begin to precipitate in the alcohol in the form of white, gelatinous strings or clumps.
    You can separate and remove the DNA thus obtained, by spooling it onto a plastic straw or a wooden stick.
    This is all about extracting DNA from plant cells that you can perform at home.
    Thanks for watching.

    Background and Troubleshooting for RT-PCR

    Webinar Abstract:
    Real-time PCR, or quantitative qPCR, is a commonly used molecular biology lab technique to determine the actual amount of PCR product at a given cycle. For quantitative reverse transcription PCR (RT-qPCR), the starting material is RNA, which is then transcribed to cDNA by a reverse transcriptase prior to the qPCR assay. Gene expression is a common application for qPCR, and amplification through RT-qPCR is necessary to detect and quantify gene expression from small amounts of RNA. This webinar will present the basics of RT-qPCR and tips and tricks for performing RT-qPCR experiments.

    Learning Objectives:
    1. Understand the basics of RT-PCR, including how it is used for quantitating gene expression and its advantages over other methods
    2. Explore successful optimization strategies and troubleshooting tips to achieve better results

    BL21 E. coli are by far the most obnoxious bacteria genetic engineers usually work with for 1 simple reason. They are maddeningly difficult to modify and load with new DNA. This wouldn't be an issue if they weren't also one of the best types for producing proteins en mass, and as such have application in everything from pharmaceutical production, to producing ingredients for foods. But after a few years of tinkering with it I finally found a protocol that reliably fixes this irritating issue, and makes it easy to transform them reliably.

  • Building More Useful CRISPR-Cas Technologies

    45:12

    The Kleinstiver lab is focused on developing new and improved gene-editing technologies. During his presentation, Dr. Kleinstiver discussed protein engineering strategies applied by his team to improve on-target activity, targeting range, and specificity/safety of CRISPR/Cas9 nuclease.

    Targeting range is a limitation imposed by protospacer adjacent motif (PAM) sequences on the access of Cas9 nuclease to edit broad genomic sites. Therefore, Dr. Kleinstiver’s team engineered changes in amino acid residues relevant for PAM recognition. In addition, to expedite the screening of Cas9 nuclease libraries, his team developed a high-throughput PAM determination assay for screening (HT-PAMDA) Cas9 PAM specificities. This approach has enabled the Kleinstiver team to identify various forms of Cas9, including SpG (NGN) and later SpRY (NAN), with relaxed PAM requirements.

    Cas9 nuclease’s off-target effects limit the therapeutic application of current gene editing tools due to potential unwanted genomic changes. With newly engineered Cas9s having relaxed PAM requirements, a critical question that the Kleinstiver lab had to address was the potential for increased off-target activities. Using a previously developed assay, GUIDE-seq, they confirmed that SpG and SpRY activities targeted an increased number of off-target sites. Introducing high-fidelity changes in SpG and SpRY sequences allowed the reduction of off-target edits, thus improving their safety.

    What are some of the benefits of these newly developed Cas9 nucleases? First, Dr. Kleinstiver shared how nucleases with minimal PAM requirement can facilitate base-editing and prime-editing approaches, which require the Cas nuclease to access exact genomic sites. Lastly, he shared how his lab leverages these new enzymes even as molecular tools in vitro, which provide greater flexibility for cloning approaches.

  • PacBio Targeted Sequencing of Long Amplicons Using PCR or Hybrid Capture

    44:22

    Targeted sequencing experiments commonly rely on either PCR or hybrid capture to enrich for targets of interest. When using short read sequencing platforms, these amplicons or fragments are frequently targeted to a few hundred base pairs to accommodate the read lengths of the platform. Given PacBio’s long readlength, it is straightforward to sequence amplicons or captured fragments that are multiple kilobases in length. These long sequences are useful for easily visualizing variants that include SNPs, CNVs and other structural variants, often without assembly. We will review methods for the sequencing of long amplicons and provide examples using amplicons that range from several kilobases up to 17 kilobases. In addition, we will review methods for the capture of fragments longer than 5 kb using hybrid capture technologies and show an example in which a panel of 35 Alzheimer’s Disease genes are captured.
