Ensuring Research Integrity: The Importance of Contamination-Free Cell Lines Key Takeaways on HeLa Cell Line Integrity

Cell line contamination affects 15-35% of laboratory cultures, compromising research validity and wasting valuable resources. HeLa cells are the oldest and most commonly used human cell line in biomedical research, contributing to over 110,000 scientific publications. Authentication through STR profiling is the gold standard for human cell line verification, providing unique genetic fingerprints.
