The StockMarks™ for Dogs Canine Genotyping Kit is part of a complete solution for animal parentage typing and genotyping employing short tandem repeats (STRs), also referred to as microsatellites. Microsatellite markers are evenly distributed across genome. They are highly polymorphic and they can be identified within DNA samples using PCR.

The StockMarks™ kits employ a proprietary PCR process for amplification of the microsatellite markers using fluorescent dyelabeled primers. The StockMarks™ for Cattle and StockMarks™ for Horses kits amplify the microsatellite markers recommended by the International Society of Animal Genetics (ISAG), while the StockMarks™ for Dogs kit amplifies the microsatellite markers recommended by the American Kennel Club (AKC).
