qPCR reagents enable discoveries across a multitude of disciplines. Although they are ubiquitous, they are not all created equal – many fall short in multiplexed assays, limiting their utility in this important area. In the design and development of our Luna® qPCR portfolio, we took a systematic approach, creating a novel data visualization method that drove our development efforts. We also engineered a new, thermostable, WarmStart®reverse transcriptase (RT) that facilitates robust performance of the Luna One-Step RT-qPCR products, even in multiplex applications.
High fidelity polymerases are everywhere—but why would you need a high fidelity ligase? And what do we even mean by “fidelity” when we’re talking about ligation? NEB Scientist and ligase expert Greg Lohman discusses mismatch ligation by DNA ligases and the molecular diagnostics applications that depend on the use of high-fidelity DNA ligases like NEB’s new HiFi Taq DNA Ligase to detect single base differences in DNA*.
* intended for use in molecular diagnostics applications that depend on high fidelity nick ligation. This is not a substitute for T4 DNA Ligase and is not suitable for cloning applications or adaptor ligation/NGS library prep.
As NGS library prep throughput increases, DNA shearing has become a more significant bottleneck in the workflow. Current methods are challenged with instrumentation and consumables cost, lack of scalability, DNA damage and bias. In this webinar, we provide an overview of the current fragmentation strategies, and introduce a new enzymatic DNA fragmentation reagent that is fully integrated into the library prep workflow. This innovative method utilizes a simple protocol for a wide range of input amounts and GC content and yields reliable results.
During this webinar, we will discuss various options for analyzing data using pipelines specifically designed for the NEBNext Direct target enrichment approach, including open-source tools for the utilization of unique molecule identifiers (UMIs) for identification of PCR duplicate molecules and consensus error correction for improved variant detection. We will showcase the ability to analyze NEBNext Direct data using various solutions that allow the pipelines to be executed by anyone through user-friendly, 3rd party software interfaces, to production-grade pipelines to be implemented by a bioinformatician.
In this webinar you will learn how to increase editing efficiency by directly introducing Cas9 ribonucleoproteins (RNPs) to cells through electroporation or lipofection. Rapid sgRNA synthesis requiring only a single user-supplied ~55mer single-stranded DNA oligonucleotide is described. Methods for assessing genome editing efficiency will be discussed including T7-endonuclease I-based methods, sequencing-based methods, and in vitroCas9 digestion.
T4 DNA Ligase is a key enzyme in molecular biology, particularly useful for its high activity in the joining of multiple DNA fragments with complementary cohesive ends or blunt ends. We have recently developed a single-molecule sequencing method to characterize end-joining fidelity (discrimination against ligating mismatched overhangs) and bias (sequence preferences) for short cohesive ends in a high throughput manner. This method allows determination of the relative frequency of all ligation products with or without mismatches, the position-dependent frequency of each mismatch, and sequence-dependent biases in ligation efficiency. We have applied the fidelity and bias data to optimize design of Golden Gate-type assemblies, allowing selection of overhang sets with minimized mismatch potential and high efficiency. Use of this data has allowed highly efficient and accurate assembly of up to 24 fragments in one pot, with the flexibility to choose junctions within native coding sequences
NEBNext Direct Custom Ready Panels employ a novel hybridization-based enrichment approach to selectively enrich nucleic acid targets in a single-day workflow. We have designed and optimized probes specific to the full exonic content of human genes associated with cancer, neurological disorders, autism, cardiovascular disease and other conditions. These are designed, balanced, and pooled on a per gene basis, and can be combined into NEBNext Direct Custom Ready Panels, allowing rapid turnaround of specific custom gene subsets. Here, we present the ability to rapidly deploy custom gene panels across a variety of panel sizes and content, while maintaining high specificity, uniformity of coverage across target content, and sensitivity to detect nucleic acid variants from clinically relevant samples.
