On September 18, 2017, NCBI staff will offer a workshop on EDirect, NCBI’s suite of programs for easy command line access to literature and biomolecular records. To join the workshop, please register.
NOTE: This is an in-person workshop at the National Library of Medicine on the NIH campus in Bethesda, MD, USA. The course is limited to 22 participants.
Sequence Viewer 3.22 has several new features, improvements and bug fixes, including improved rendering on BAM and cSRA tracks. For a full list of changes, see the Sequence Viewer release notes.
Sequence Viewer is a graphical view of sequences and color-coded annotations on regions of sequences stored in the Nucleotide and Protein databases.
NCBI is pleased to announce the initial data release of RefSeq Functional Elements, a resource that provides RefSeq and Gene records for experimentally validated human and mouse non-genic functional elements. Data can be accessed via Gene, Nucleotide, BLAST, BioProject, Graphical Displays and FTP.
A common task facing geneticists is to assay for sequence changes at particular locations in genes. These assays are often looking for changes in the coding exon of genes, and the target sequences are typically amplified using PCR from genomic DNA using a pair of specific primers. In this article, we will show you how to use NCBI Reference Sequences and Primer-BLAST, NCBI’s primer designer and specificity checker, to design a pair of primers that will amplify a single exon (exon 15) of the human breast cancer 1 (BRCA1) gene.
Here are the steps to follow to design primers to amplify exon 15 from human BRCA1:
