Applied DNA Sciences claims to have closed the loop on traceability for Egyptian Pima using DNA-based genotyping assays for cotton authentication from ginned fibre to finished textile product.

Those assays – an investigative (analytic) procedure – have been used to verify fibre and will be extended to yarn, fabric and finished goods in an ongoing validation programme.

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 three years related to the validation of a known library of cotton cultivar standards.
