SNPYGoat Kit

Multiplex primer extension assay for identification of paternal lineages in domestic goat (Capra hircus)

The IDENTIFICA SNPYGoat Kit is a rapid and robust multiplex PCR/primer extension assay to genotype a set of goat Y chromosome single nucleotide polymorphisms (SNPs). Four diagnostic SNPs located in two flanking domains of the SRY gene (promoter region and 3 untranslated region) were selected to allow the discrimination of the four Y-chromosomal haplotypes Y1A, Y1B, Y1C and Y2 identified so far in domestic goat populations.

The detection of SNP variants is based on the SNaPshot single-base sequencing (also known as minisequencing), which consists in using dideoxynucleotides (ddNTPs) for singlebase extension of an unlabeled primer that anneals one base upstream to the relevant SNP.

An auxiliary software was developed to simplify the process of haplotype identification directly from the sample profile.
