Absence of HeLa cell contamination in 169 cell lines derived from human tumors

J Natl Cancer Inst. 1977 Feb;58(2):209-14. doi: 10.1093/jnci/58.2.209.


Numerous cell lines derived from human tumors are not HeLa contaminants. Of 192 lines established in this or other laboratories, 169 lines were found to be G6PD type B. Twenty-three lines were type A as HeLa; three of these were of Negroid origin. There is reasonable doubt that the remaining 20 lines will all be shown to be confounded with HeLa.
