Patent ID: 7541159

Claim:
A method of determining total urokinase concentration in a sample containing at least one of an active or inactive form of urokinase, comprising: generating at least one immunological composition directed against at least one of a first peptide with SEQ ID NOs: 1, 2, 3, 4, 5 or 6; generating at least one immunological composition directed against at least one of a second peptide with SEQ ID NOs: 7, 8, 9, 10, 11 or 12; and generating at least one immunological composition directed against at least one of a third peptide with SEQ ID NOs: 13 or 14; contacting aliquots of said sample separately with each of said at least one immunological composition; and measuring quantity and comparing type of said at least one immunological composition bound in each of said aliquots to determine a concentration of said at least one of said active or inactive form of urokinase, wherein each of said at least one immunological composition binds to said at least one of said active or inactive form of urokinase and is indicative of said concentration of the form that is bound thereto, wherein the total of said concentration of said at least one of said active and inactive form of urokinase represents the total urokinase concentration in said sample.
