seven different test systems were utilized to investigate the genetic activity of chromium compounds : infidelity of dna replication in vitro by dna pol alpha from calf thymus , damage of dna detected by alkaline elution in treated mammalian cells or in dna purified and treated in vitro , dna repair synthesis in mammalian cells in vitro detected by autoradiography or scintillation counting after labelling with [ 3h ] dthd , gene mutations in the salmonella typhimurium ames test , gene mutations ( 6tg resistance ) in cultured hamster cells , sister-chromatid exchanges in different rodent cell cultures , and transformation to anchorage-independent growth of hamster cells in vitro ( soft-agar assay ) .
