A protein tyrosine kinase with an apparent Mr of 60,000 was highly purified from bovine spleen and used to phosphorylate poly(Glu, Tyr) (4:1) on tyrosine residues for the study of phosphotyrosyl protein phosphatases from this tissue. About 70% of the phosphotyrosyl protein phosphatase activity in ex
