PIRA PCR designer for restriction analysis of single nucleotide polymorphisms.

UNLABELLED: Primer-introduced restriction analysis (PIRA-PCR) is widely used to detect Single Nucleotide Polymorphisms (SNPs). To create artificial Restriction Fragment Length Polymorphism (RFLP), a mismatch is usually introduced near the end of the primer that is close to the mutation of interest. We describe in this report a www-based computer program that screens for the suitable mismatches, designs the primers, lists the appropriate restriction enzymes and other related information. AVAILABILITY: The computer program, with related descriptions, is available at http://cedar.genetics.soton.ac.uk/public_html/primer2.html.
