New GMO detection method uses bioluminesence

Details of a new method for detecting GMOs developed by the UK molecular diagnostics company, Lumora (Ely, Cambridgeshire), have been published in the journal, BMC Biotechnology. The method is more sensitive than the usual polymerase chain reaction (PCR) methods employed to detect GMOs and can also be used in the field and throughout the food processing chain. It uses bioluminescent real time reporter (BART) technology and loop mediated isothermal amplification (LAMP). The combination of these techniques is able to recognise 0.1% GM contamination of maize, far below the current EU limit of 0.9%, claims Lumora. It is also more tolerant of contaminating polysaccharides, allowing less stringent sample preparation than for PCR analysis.
