Within the food manufacturing and testing industry, 1% DNA is considered the reasonable threshold for distinguishing contamination from gross adulteration when sampling meat derived products.
The genesig 1% Level DNA Speciation Controls are a high-quality source of DNA validated for use in qPCR experiments. The DNA has been extracted from animal tissue and analysed to confirm the absence of PCR inhibitors. Following this, the material is mixed with background DNA from an alternative animal source and subjected to a regime of quantitative tests before being packaged and supplied in a lyophilised format. Our 1% Level DNA Speciation Controls are a useful tool for confirming the accuracy of DNA speciation testing strategies.
Testing for meat adulteration poses many technical challenges regardless of the approach used. DNA testing via qPCR is the gold-standard for speciation, however one of its challenges is that meat (i.e. protein) content is not directly assayed; DNA levels are used as a surrogate marker instead. This can pose problems when attempting to validate the quantitative accuracy of DNA speciation tests. This is because 1% mixes of meat do not always translate to 1% at the DNA level. In these circumstances genesig 1% Level DNA Controls serve as an invaluable control material for qPCR speciation testing.
