13. September 2018 / Definite developments in DNA testing

Impetus Bioscience – ICA Bremen’s partner for cotton DNA testing services – can now offer exact quantitative measures of genetically modified cotton in samples, as well as more accurate testing of finished textiles. The developments were made over the last few months in response to increasing demand for transparency within the supply chain and from consumers.

Dr Hermann Rüggeberg of the DNA analysis company in Bremerhaven said; “We have expanded our testing capabilities to identify many changes in the DNA of cotton. Most significantly, the distinction between the lower and higher percentage of genetically modified cotton present in the sample.”

“Our analytical process involves exact quantitative measurements, only possible by using state-of-the-art real-time ‘polymerase chain reaction’* technologies alongside our other testing methods. For example, specific DNA sections of genetically modified insect resistant cotton can now be identified and quantified.”

Previously, a positive screening result indicated a genetic modification, which only allowed a positive or negative diagnosis of genetically modified cotton. These new methods of analysis allow the immediate and definite classification of genetically modified plants.

Bill Kingdon, ICA Bremen’s Managing Director said; “We are excited about the developments made by Impetus Bioscience and hope this will further strengthen our partnership with them by expanding the services we offer to the global cotton community.”

*Polymerase chain reaction is a method of making multiple copies of a DNA sequence, involving repeated reactions with a polymerase.
