Colony PCR

Identification of isolated colonies and ISO 7218

All horizontal methods for the search for pathogenic bacteria include, within the ISO standard, a paragraph related to the methods of identification / confirmation of presumed positive colonies. ISO 7218, one of the fundamental standards for the regulation of microbiological analyzes, indicates the operating procedures for the identification of colonies and includes molecular methods.

All PATHfinder Real-Time PCR kits proposed by Generon are based on international scientific literature, therefore they can be used for the identification of colonies within an ISO17025 accreditation scheme based on international standards.
