Abstract：
:Chinese hamster lymphocyte cultures were supplemented with foetal calf serum (FCS) or hose serum (HS). Addition of 2-mercaptoethanol (2-ME) to cultures supplemented with these sera resulted in a marked increase lymphocyte proliferation. The PHA concentrations necessary for optimal lymphocyte stimulation were much lower in cultures supplemented with HS than with FCS. Phytohaemagglutinin (PHA) concentrations optimal for stimulation of a given number of lymphocytes in cultures supplemented with FCS often gave inhibition of similar cultures supplemented with HS.
