NCBI is retiring the e-PCR tool effective immediately. The good news is that an existing tool, Primer-BLAST, fills in nicely for the functions of both Forward and Reverse e-PCR, and has the additional benefit of de novo primer design.
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:
