STR Profiling for Mouse Cell Lines: A New Tool to Combat Cell Line Misidentification

April 02, 2020, at 12:00 PM ET


Do you trust the results of your experiments? Cell line misidentification and cross contamination have far-reaching impacts in biomedical studies, including publication retraction, credibility loss, data invalidation, and financial cost. While human cell line authentication has been addressed with a short tandem repeat (STR) profiling, up until now there has not been a validated method for identifying mouse cell lines beyond the species level. In this webinar, we will describe ATCC’s STR profiling services, focusing on a new mouse STR profiling method. After the presentation, we invite you to join in on the discussion as a panel of ATCC cell line authentication experts answer your questions.

Key Points

  • Cell line authentication is a critical requirement to receive funding for research, publish papers in scientific journals, and validate in vitro studies for preclinical testing
  • ATCC offers human and mouse STR profiling services for cell line authentication
  • The mouse STR profiling method was developed by NIST in collaboration with ATCC and 10 independent laboratories
