Genetic determination of species through DNA barcoding

Accurately identifying species requires the input and leading expertise of taxonomists and ecologists. Beyond the difficulty of accessing such expertise, other factors can hamper specific identification, including the complexity of certain morphological characters, inaccuracies in some identification keys or the presence of cryptic diversity. Furthermore, identification using traditional approaches is only possible for specimens available in an unprocessed state, i.e., in their natural biological state, or freshly harvested, and not as extracts or formulated ingredients in a commercial product. To overcome these limitations, DNA barcoding is a fast, inexpensive and accurate method whose use has grown steadily over the last 20 years. It is particularly useful for identifying species at different life stages, fragments of organisms lacking diagnostic characteristics, processed products, and even traces of DNA in the environment.

This is how the CRBM developed its expertise in DNA barcoding, recognizing its wide range of applications and usefulness across various fields and markets. Beyond its applications in life sciences and medicine, such as identifying and tracking pathogenic organisms, the method is also effective for identifying and monitoring invasive non-native species and endangered native species, as well as for market surveillance in food authentication by detecting contamination or ingredient substitution.

The CRBM offers this expertise as a service in support of our clients’ operations, or as part of collaborative research and development projects.
