AAPN member Applied DNA Sciences are about to begin ending a controversy that has been dogging the textile industry for years by closing the loop on traceability for Egyptian Pima using DNA-based genotyping assays for cotton authentication.

These assays have been used to verify fiber and will be extended to yarn, fabric and finished goods in an ongoing validation program. The Egyptian Pima developments join and expand a series of US Pima cotton assays performed within Applied DNA testing services and are based on work conducted over the past 3 years related to the validation of a known library of cotton cultivar standards.
