APDN Uses SigNature® DNA To Mark Raw Cotton Fiber

Stony Brook, N.Y.-based Applied DNA Sciences Inc. (APDN), a provider of DNA encrypted and embedded authentication solutions, reports it has successfully marked more than 500,000 pounds of raw cotton fiber with its patented SigNature® DNA solution — the largest use of a commercial DNA marker to date — as part of a collaborative pilot study conducted in partnership with a major US cotton producer. 

The project complements APDN's Biomaterial™ Genotyping platform to track and authenticate cotton's native DNA, which can be used to identify the fiber's plant cultivar and country of origin. SigNature DNA markers may be used to track specific natural or man-made fiber batches through to finished textiles and apparel, including technical textiles and nonwovens.
