Authentication

Cell models and microbial strains are fundamental tools for drug discovery, quality control, and assay development. To preserve the integrity, reproducibility, and validity of data generated in biomedical research, it is essential to ensure that these cultures are properly authenticated prior to and during their use.

ATCC is committed to improving the authentication of cell lines and microbial cultures. Browse our resources to explore the current best practices for validating, storing, and handling biological materials and how these techniques support data integrity and reproducibility.
