Epitope - A part of a foreign organism (or its proteins) that is being recognized by the immune system and targeted by antibodies, cytotoxic T cells or both.

Epitope was also once the name of a publicly traded company headquartered in Beaverton, Oregon. It began in 1979 as Immunologic Associates, Inc., a parentage testing laboratory, and incorporated two years later as Epitope, Inc. The initial public offering was in 1986 at the beginning of the "biotech boom" and stock traded under the symbol EPTO on NASDAQ.

Its official end was effective September 30, 2000, the result of a merger with STC Technologies, becoming OraSure Technologies, Inc. According to the company, "Combining Epitope and STC will leverage our expertise in oral fluid technology, infectious disease testing, and substance abuse testing. Together, we intend to bring diagnostic solutions for the new millennium."

Pictured above-right is the 8505 S.W. Creekside Place [Beaverton, Oregon 97008] headquarters facility. For a time, when the company was expanding, Epitope also occupied a good portion of 8205 S.W. Creekside Place.

This site is intended to memorialize a company that was a huge part of many people's lives. It is dedicated to the historic (or nostalgic) Epitope and not OraSure Technologies. If you are seeking information about OraSure, click here.
