Applied DNA bags patent for authenticating Pima products

The US Patent and Trademark Office issued the “Methods for Genotyping Mature Cotton Fibres and Textiles” patent for PimaTyping authentication of extra long staple or Pima cotton-based products to for Applied DNA Sciences.

“This patent encompasses the identification of genetic differences among various Extra Long Staple (ELS) cotton cultivars,” Applied DNA Sciences said in a press release.

Unlike APDN’s FiberTyping patent that identifies the genetic differences between two cotton species, G. barbadense and G. hirsutum, this new patent enables identification of minor genetic differences among various cultivars under the G. bardadense species.

“This patent makes it possible to distinguish US Pima cotton from other ELS cottons grown around the world, such as Egyptian Giza cotton or Chinese Xinjiang ELS cotton,” it added.

The portfolio of cotton authentication technologies will be important to growers, ginners, manufacturers, brands, retailers and governments.

Using this new assay, suppliers can assure their “American Pima” labels, even when their products are manufactured off shore.

With SigNature T marking and authentication, suppliers of cotton to the US military can prove their cotton is of American origin, in compliance with the Berry Amendment.

"This patent is an important milestone, because we have proven that we can extract DNA from samples of mature cotton fibre taken from a textile item, and verify its origin, said Benjamin Liang, chief scientific officer.

He added, “We are in the process of developing commercial testing kits, and in the future, will be able to provide authentication services on site.

“Given, the high resolution of this test, we offer customised assay development programs for PimaTyping, which is a complement but not a substitute for FiberTyping.”

"This is valuable information for growers as well as manufacturers and consumers to know that a product labeled as ELS, can now be verified to its original source,” Cannon Michael, president at Bowles Farming said.

“As a cotton grower, we pride ourselves on the quality, integrity of the Pima ELS fibre that is grown here in the San Joaquin Valley,” he too added by saying.

He observed, “More importantly, the future of cotton production is protected because products labeled as Pima ELS can be verified through DNA technology." (AR)
