Abstract excerpt
Biological characterization of a human colon adenocarcinoma cell line deficient in thymidylate synthase (TS-) is described. The clone, designated TS-C1/C1, was derived from the parental line GC3/C1 by selection in medium containing aminopterin, thymidine (dThd), and low concentrations of 5-formyltetrahydrofolate (5-CHO-H4PteGlu), and was subsequently reselected by single-step cloning in 500 microM methotrexate in...
