Summary
Monoclonal antibodies against urinary urokinase were obtained by immunizing mice with purified human high molecular weight urokinase. Five antibodies were selected and denominated MPW1UK, MPW2UK, MPW3UK, MPW4UK, and MPW5UK, respectively. All selected antibodies reacted with high and low molecular weight urokinase. Cleavage of the low molecular weight paranitroanilide substrate pyro-Glu-Gly-Arg-pNA by urokinase was not inhibited by the antibodies and only one antibody (MPW5UK) inhibited plasminogen activation by urokinase. The ability of MPW5UK to bind to coated urokinase was 100-fold higher than that of the other antibodies. MPW5UK was used to prepare an immunosorbent for the purification of urokinase antigen from freshly voided crude urine. One-chain prourokinase was separated from two-chain urokinase by chromatography of the urokinase antigen containing mixture on agmatine Sepharose. As judged by SDS gel electrophoresis one-chain prourokinase as well as two-chain urokinase were purified to apparent homogeneity by this two-step procedure; the yields were 18% and 47% for single-chain prourokinase and two-chain urokinase, respectively, as calculated from total urokinase antigen contained in the starting material.
