Detection and analysis of a glucose 6-phosphate dehydrogenase phenotype B cell line contamination.
Eight of approximately 100 cell lines derived at the Scott and White Clinic from human solid tumors were found to have the same phenotypes when analyzed for 15 polymorphic enzymes at the Sloan-Kettering Institute for Cancer Research. These data were confirmed at the M. D. Anderson Hospital and Tumor Institute. The similarity was supported by cytogenetic studies at both institutions. The chronology of the establishment of these cell lines and isoenzyme and cytogenetic studies indicated that six of these lines have cross cell contamination. These include SW-527 and SW-613 mammary carcinomas, SW-598 meningioma, SW-608 astrocytoma, SW-732 cervix carcinoma, and SW-733 bladder carcinoma. Our data supported the authenticity of SW-480 and SW-620, which were derived from a colon carcinoma and its metastasis, respectively, from the same patient.
