Molecular biomarker analysis — Detection of animal-derived materials in foodstuffs and feedstuffs by real-time PCR — Part 9: Goose DNA detection method
Product Details
The method can be applied to distinguish domestic breeds of swan goose (Anser cygnoides domesticus) and domestic goose (Anser anser domesticus) from domestic chicken, duck and turkey which are the most common adulterants of foie gras.[1] It is also able to differentiate the domestic goose from other high-end domestic poultry meats (quail, pigeon, pheasant).
The target sequence is a partial fragment of the Anser cygnoides isolate SCWG-2014 breed Sichuan white goose unplaced genomic scaffold, GooseV1.0 scaffold320 (i.e. GenBank accession number NW_025927981.1)[2], which is present as a single copy per haploid genome. The provided PCR assay for this target has an absolute limit of detection of five copies per reaction, with = 95 % confidence at this concentration (LOD95 %).
