title: Absence of HeLa cell contamination in 169 cell lines derived from human tumors.
abstract: 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.
