Cross‐contamination of the human salivary gland <scp>HSG</scp> cell line with HeLa cells: A <scp>STR</scp> analysis study

Abstract

Short tandem repeat analysis revealed that HSG was contaminated by the HeLa cell line. Furthermore, because genotyping of the original HSG cell line was not performed during its establishment, it will be difficult to authenticate an uncontaminated sample of HSG.
