title: beta2-Microglobulin from normal and leukaemic guinea-pig lymphocytes.
abstract: beta2-Microglobulin has been isolated in useful quantities from the urine of strain-2 guinea-pigs after either treatment with sodium chromate or induction of the L2C leukaemia. Antibodies raised against the beta2-microglobulin were used to set up a radioimmunoassay which measured its export into culture fluid by normal and leukaemic lymphocytes. Material containing beta2-microglobulin was also obtained by digestion of the lymphocytic surfaces with papain; fractionation demonstrated both free and combined forms, with no qualitative difference between those from normal and those from leukaemic cells.
