Monoclonal antibodies have been developed which specifically bind the PSA-ACT complex without significant cross-reactivity with PSA, ACT or CG-ACT. The antibodies were generated using a unique immunogen comprising a PSA-ACT complex having bound to monoclonal antibodies against PSA and monoclonal antibodies against ACT. It is theorized that the antibodies against PSA and ACT block immunodominant sites on the PSA-ACT complex. The antibodies generated against the unique immunogen specifically bind the PSA-ACT complex, but have no significant cross-reactivity with either PSA or ACT. The monoclonal antibodies of the present invention can be used in immunoassays to specifically detect PSA-ACT in a sample.
