Ask the Expert is a feature on the Cell Culture Dish where both industry and academic experts answer your questions. A range of topics is covered and suggestions for future Ask the Expert sessions are welcome.

Our Next Session –

The Role of Cell Line Authentication in Today’s Biomedical Research World

Inadvertent cell line contamination is a serious concern for many researchers. Failure to monitor cell lines for contamination may result in compromised data. Current estimates are that 18% to 36% of all active cell lines are either cross-contaminated or misidentified.1 This level of concern has led a number of journals to actively encourage cell line authentication prior to submission for publication. Cell line authentication testing is a good quality control step for any laboratory utilizing human cell lines and/or stem cell lines. If you want to set your research on a strong foundation, please join us for this week’s Ask the Expert – “The Role of Cell Line Authentication in Today’s Biomedical Research World,” and ask any questions you have about Cell Line Authentication.

Hosting this week’s session is Erin M. Hall, M.S., Director, Cell Line Authentication Services, Genetica DNA Laboratories, LabCorp Specialty Testing Group.
