Human Diagnostics
Human Diagnostic Antigens
The market for human antigens and tumor markers is estimated at approximately $2 million, annually. We believe we currently are the largest supplier in our market, and all of our revenues to date have come from sales of these products. We expect to continue adding products to our diagnostic protein line. Our primary competitor for supply of human pituitary antigens is Dr. Albert Parlow, a professor at UCLA. We do not currently sell our products under contracts. Sales are made generally on open account on a purchase order basis.
