APDN Launches Pima, ELS Cotton Authentication Tests

Applied DNA Sciences Inc. (APDN), a Stony Brook, N.Y.-based provider of DNA encrypted and embedded authentication solutions, has completed a feasibility study for the development of Pima cotton authentication processes on behalf of Phoenix-based Supima, a promotional organization comprised of American Pima cotton growers. APDN has developed and now is marketing two genetic assays — FiberTyping™ for distinguishing Pima cotton from Upland cotton, and PimaTyping™ for differentiating extra-long-staple (ELS) cotton grown in different regions of the world.

Pima is a generic name for ELS cotton produced in the United States, Australia and Peru and a few other regions. Pima or ELS cotton differs from Upland cotton in terms of staple length and strength of the fibers.

“We have been successful in developing a genetic assay to distinguish between Pima (including Supima®) and Upland cotton in fiber and fabric,” said Dr. Benjamin Liang, chief technology officer, APDN, speaking about FiberTyping. “The proprietary, patent-pending methodologies are very specific and robust and similar to what has been used to track human lineage of archaeological remains.”

The tests will be especially valuable in verifying Pima and ELS cotton content in yarn and fabrics processed by overseas apparel makers and exported into the United States, as such apparel made from US cotton receives favorable tariff treatment under numerous trade agreements.

“We believe that the genetic assays developed by APDN to detect Pima cotton DNA in fiber as well as fabric are remarkable discoveries which will help us provide a higher level of quality assurance and authentication to all participants in the value chain, from the cotton grower to the end consumer,” said Jesse Curlee, president, Supima. “We believe that APDN’s developments will alter the face of the global cotton industry and favorably affect the demand curve.”
