The department of biotechnology (DBT) in collaboration with Hyderabad based centre for DNA fingerprinting and diagnostics (CDFD) has developed a diagnostic kit for rapid detection of genetically modified (GM) traces in food by going to the level of DNA. Earlier a diagnostic developed by the central institute for cotton research could detect by going only to the level of protein. ”If this new kit is used it can resolve the claims of genetic contamination of conventional crops by GM crops. We can also use this diagnostic kit for checking imported food which may contain traces GM matter,” said, DBT secretary, MK Bhan.
