VigyanLLM's allele-specific PCR tool provides automated allele-specific primer design for PCR research. Runs entirely on-premises via Docker deployment with no data egress.

Enhanced Allele Discrimination

VigyanLLM uses advanced allele-specific PCR design techniques to maximize discrimination between alleles. The platform introduces an additional intentional mismatch at the -2 or -3 position from the 3' end, which destabilizes non-target amplification while maintaining efficient target amplification. Combined with Tm optimization and dimer screening, this approach produces allele-specific assays with high specificity and low false-positive rates.

Frequently Asked Questions: allele-specific PCR

How does allele-specific PCR work?

Allele-specific PCR (also called ARMS-PCR or AS-PCR) discriminates between alleles by placing the discriminatory nucleotide at the 3' end of the primer. DNA polymerase extends efficiently only when there is perfect complementarity at the 3' end, so the primer amplifies one allele but not the other. VigyanLLM designs allele-specific primers with optimized 3' positioning, introduces intentional mismatches near the 3' end to enhance specificity, and validates the assay design against reference genome databases.
