Gen-Probe Inc. (NSDQ:GPRO) bought Waukesha, Wis.-based GTI Diagnostics in a self-funded $53 million cash deal.
The acquisition allows the San Diego-based company to expand its transplant diagnostics business, according to Gen-Probe.
GTI develops medical diagnostic assays for the transplantation, blood bank and specialty coagulation markets. Its human leukocyte antigen, or HLA, antibody detection products are already sold by Gen-Probe under the Lifecodes brand, but the company has also commercialized a number of other HLA-related testing products, including serological typing trays, enzyme immunoassays and molecular typing products for donor-recipient matching, according to Gen-Probe.
GTI was owned by Cleveland-based private equity firm the Riverside Co. and investors, including the company’s founders.
