The National Center for Biotechnology Information (NCBI) provides one of the most extensive sets of web-based tools for biological research. The tools are indispensable when planning genomics experiments, including for qPCR, NGS, and CRISPR. In this presentation, Dr Matt McNeill takes a practical look at getting started with the wealth of NCBI tools, and shares some relevant tips to help you sift through the tools and options that we regularly use. In particular, he focuses on commonly adjusted parameters that will allow you to more effectively use the powerful Basic Local Alignment Algorithm Tool (BLAST) to identify off-target hybridization/annealing events. Dr McNeill also covers practical examples using NCBI tools to design assays.
