Application Notes

  • High throughput silica membrane-based viral RNA extraction using positive pressure

    An application note about automated purification of viral RNA with Tecan's Resolvex A200 positive pressure workstation and MACHEREY-NAGEL's NucleoSpin 96 Virus Kit.

  • Restriction Endonucleases from NEB

    With over 40 years of offering restriction enzymes to the research community, NEB has earned the reputation of being a leader in enzyme technologies. Working continuously to be worthy of that distinction, NEB strives to develop enzymes of the highest purity and unparalleled performance.
  • Namocell's Two-Step Rare Cell Isolation

    Rare cell isolation can be very challenging using conventional cell isolation methods when the target cell population frequencies are less than 1% such as circulating tumor cells (CTCs) in blood or low transfected GFP-positive cells within a pool. Although cell sorting is typically performed to isolate rare cells, this is not ideal due to factors that may compromise the rare cell viability and recovery including long sorting time, high pressure (typically more than 20 psi), and large dead volume.
  • Ultra Low Sample Input with Namocell

    Effectively obtaining a single cell is key for single-cell transcriptomics, proteomics, and genomics. In this application note, we evaluate the single cell isolation efficiency of a 100 cells input with an adherent and non-adherent cell lines.
  • Namocell's SMART-Seq HT Protocol

    Single-cell cDNA Synthesis with Namocell Single Cell Dispenser and 1/4 reaction volume of Takara SMART-Seq® HT Kit.
  • A Practical Guide to Analyzing Nucleic Acid Concentration and Purity with Microvolume Spectrophotometers

    Microvolume spectrophotometers (MVS) are commonly used for the analysis of nucleic acid (NA) samples. They require a small sample volume (0.5–2.0 μl) and are economical, convenient and widely commercially available. Typically, they can measure NA concentrations as low as 1 ng/μl and they are compatible with various assays for all types of NA and proteins. Concentration and purity readings from MVS are often accepted as fact; however, a more detailed understanding of the readings can provide meaningful insight into the quality of the sample and its suitability for downstream applications. This technical note provides detailed explanations and guidance on how to interpret and use MVS measurements, with a focus on samples purified using silica spin columns.
  • Generating Clonal GFP Cell Lines

    Generating a clonal GFP cell line typically requires first sorting GFP positive cells with a cell sorter. Then GFP positive cells are cultured for several days to recover from the high pressure damage caused by the cell sorter. Clonal GFP cells are finally obtained by manual limited dilution at 1 cell per well. In this application note, Namocell Single Cell Dispenser was used to directly isolate single GFP positive cells into 96-well cell culture plate. Due to the low pressure of the Namocell Single Cell Dispenser, clonal GFP cell lines can be generated in a single step.
  • Single B Cell Genomics

    By use of a Namo Single Cell Dispenser, activated single B cells were isolated. Single B cell cDNA was suitable for both downstream single cell transcriptome library generation and PCR of the full length of immunoglobulin heavy and light chain variable domains.
  • Minimal Cell Input

    Obtaining a single cell is a critical step for single-cell transcriptomics, proteomics, and genomics. Traditional cell sorters have provided a powerful tool for sorting cells. However, it typically requires a large amount of cells. In this application note, Namocell Single Cell Dispenser was used to evaluate the single cell isolation efficiency of 100 minimal cell input with an adherent and non-adherent cell line.

  • Single Nuclei Dispensing

    Using a Namocell Single Cell Dispenser, single nuclei were isolated and verified under a fluorescent microscope. Isolated single nuclei are suitable for single-nucleus RNA sequencing. Complete your details and receive a copy of the application note in your inbox.
  • NEBNext Direct® Custom Ready Panel technology analyzed using NextGENe®

    With targeted panels becoming an excellent alternative for whole exome and genome Next Generation Sequencing (NGS) there is an increasing need for highly flexible and optimized custom panels. The NEBNext Direct technology in conjunction with NextGENe software represents a high-quality solution for generation and analysis of sequencing data for identification sequence variants present in a user-friendly manner.

  • Mechanical DNA Fragmentation with the Q800R2 Sonicator

    The Qsonica Q800R2 Sonicator offers an alternative method for mechanical DNA fragmentation for Illumina TruSeq® Library Preparation Kits.

  • Restriction Enzymes for Droplet Digital PCR (ddPCR)

    NEB has evaluated a number of restriction enzymes for simple genomic DNA fragmentation in droplet digital PCR assays. This list is not meant to be exhaustive, but provides a starting point for validated enzymes with some simple usage guidelines. Each restriction enzyme listed below was successfully used for a ddPCR digest directly in the Bio-Rad® Droplet Digital SuperMix.

  • Analysis of chromosomal aberrations and recombination by allelic bias in RNA-Seq

    Read this publication in Nature Communications about the successful RNA purification for downstream RNA sequencing with the NucleoSpin RNA Plus Kit.

  • Characterize Immune Checkpoint Proteins and T Cell Exhaustion Using Multiplex IHC

    Advances in immuno-oncology have successfully led to novel cancer therapeutics with favorable patient responses that are more durable than conventional cytotoxic chemotherapy (1). However, not all patients respond to immunotherapy; therefore investigators are trying to identify clinically relevant biomarkers with the goal of developing therapeutics based on personalized medicine (2,3).

  • NucleoBond Endotoxin Free Plasmid DNA in CRISPR/Cas9 and lentiviral packaging/cell culture research

    Forward genetic screens are powerful tools for the unbiased discovery and functional characterization of specific genetic elements associated with a phenotype of interest. Recently, the RNA-guided endonuclease Cas9 from the microbial CRISPR (clustered regularly interspaced short palindromic repeats) immune system has been adapted for genome-scale screening by combining Cas9 with pooled guide RNA libraries. Here we describe a protocol for genome-scale knockout and transcriptional activation screening using the CRISPR-Cas9 system.
