Development of a nanoplate-based digital PCR assay for species identification with mixture deconvolution

In crime scenes, not all biological stains are human in origin. Some exhibits can be from pets living on the premises or from animal products used in food consumption. In addition, it could be necessary to test animal carcasses for other forensic purposes. Often such stains can include mixtures involving humans or other species. Thus, identifying and deconvoluting mixtures of species commonly found in and around a household can be crucial in forensic casework. Different molecular techniques have been employed for species identification such as immunoprecipitation, qPCR, and DNA sequencing.
