Repeated subculturing of microbiological quality control (QC) organisms can be detrimental. Each passage carries the potential for contamination, drift, and mutation, taking your culture farther and farther from the parental genotype and phenotype. ATCC provides top-quality microbial reference materials to maintain outstanding QC programs.

With ATCC Genuine Cultures^®, customers can rely on:

• Polyphasic identification and strain characterization
