Sigma-Aldrich Product Name Citrullinemia, 90102532 biological source human skin growth mode Adherent

Human Caucasian skin

Human diploid cell line derived from a young Caucasian female with Citrullinemia. The cells grow poorly when citrulline is substituted for arginine in the recommended medium and they incorporate very little 14C citrulline into cell protein. The cell line also has an abnormally low affinity for citrulline as a substrate in an in vivo assay of arginosuccinate synthetase.
