GMO ANALYSIS NOW POSSIBLE IN TEXTILE FINISHED PRODUCTS

The recently published „IWA32:2019 method“ allows the detection of genetic modifications in cotton, however, the field of application is severely restricted. Only the detection of genetic modifications is possible but neither the identification of  genetically modified cotton varieties (Events) nor the quantification of their percentage ratios.

But the most essential disadvantage is the restriction that only chemically untreated matrices like seed, raw cotton fibers or yarns can be analysed.

The key question, whether genetically modified cotton is present in ready-for-sale textile  products cannot be answered by means of the IWA32:2019 protocol – and a lot can happen on the long way from sowing to sale.

In cooperation with international cotton dealers, retailers and manufacturers of luxury garments we have analysed several hundred textile finished products. From approx. 90% of the samples we could obtain sufficient DNA to make valid statements with regard to genetic modifications, events and percentage ratios.

So for the first time Impetus Bioscience has succeeded in optimizing the methods for the extraction and purification of DNA from cotton to such an extent that the entire chain of production can be analytically supported.
