Cell Culture & Authentication Initiative

Reproducible research is a critical issue facing the life sciences community. An all too common contributor to the lack of reproducibility in biomedical research is the continued and widespread use of misidentified or contaminated cell lines, which has been reported to range from a conservative low of 15 percent to a high of 36 percent.

Short-tandem repeat (STR) profiling represents a compelling solution to this problem by authenticating human cell line unambiguously, quickly, and at low cost.

Cell Authentication Alliance

The Alliance brings together a diverse set of committed stakeholders with the sole purpose of making routine cell line authentication the new norm.  GBSI will facilitate the work of the Alliance and provide regular updates on progress throughout the research community. To learn more about the Cell Authentication Alliance, click here or email rwisman@gbsi.org.


In early 2015, GBSI launched #authenticate, a first-of-its kind awareness and activation campaign to engage key stakeholders around the powerful role cell line authentication plays in research reproducibility and fidelity. Importantly, #authenticate provides opportunities for the scientific community to get involved, demonstrate support, and help tell the story.
