blue bulletWhat does NCBI do?

Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information - all for the better understanding of molecular processes affecting human health and disease.

The new Primer-BLAST service designs more effective and gene-specific PCR primers. The tool combines Primer 3 primer design with a specificity check provided by a specialized BLAST search. For more information, see BLAST News.
