From the developer:
The FastPCR software is an integrated tools environment that provides comprehensive and professional facilities for designing any kind of PCR primers for standard, long distance, inverse, real-time PCR (TaqMan, LUX-primer, Molecular Beacon, Scorpion), multiplex PCR, Xtreme Chain Reaction (XCR®), group-specific (universal primers for genetically related DNA sequences) or unique (specific primers for each from genetically related DNA sequences), overlap extension PCR (OE-PCR) multi-fragments assembling cloning and Loop-mediated Isothermal Amplification (LAMP); single primer PCR (design of PCR primers from close located inverted repeat), automatically detecting Simple sequence repeat (SSR) loci and direct PCR primer design, amino acid sequence degenerate PCR, Polymerase Chain Assembly (PCA), design multiplexed of overlapping and non-overlapping DNA amplicons that tile across a region(s) of interest for targeted next-generation sequencing (Molecular Tagging), KASP™ (Kompetitive Allele Specific PCR) or PACE™ (PCR Allele Competitive Extension) based genotyping assay design for biallelic discrimination of single nucleotide polymorphisms (SNPs) and insertions and deletions (Indels) at specific loci, and much more.
