摘要: p56lck, a p60src related tyrosine protein kinase was recently described in murine lymphoma cell line (LSTRA), several human lymphomas and normal peripheral lymphocytes. We have purifed p56lck to homogeneity by electrofocusing followed two-step SDS/polyacrylamide gel electrophoresis. The pure identical the p56 characterized LSTRA cells used raise antibodies rabbits. This simple procedure is applicable for rapid purification of minor proteins.
