A method for purifying a recombinant protein, e.g. human tissue plasminogen activator (t-PA) from a corresponding endogenous protein of the host cell, e.g. Chinese hamster t-PA, is disclosed. The method comprises contacting a fluid containing the recombinant protein with antibodies specifically binding the corresponding endogenous protein. Monoclonal antibodies directed against and an assay for Chinese hamster t-PA are also disclosed.
