According to IVD Technology article, Gen-Probe is quite a prize, especially as it adds firepower to Hologic's automated platform:
The transaction allows Hologic to combine Gen-Probe's TIGRIS and PANTHER automation platforms and extensive menu of sexually transmitted disease tests---including the APTIMA line of chlamydia/gonorrhea, HPV, and Trichomonas products---with its strong global market presence and distribution, all targeting women's health. In addition, Gen-Probe's PROCLEIX line of HIV, HCV, HBV, and West Nile Virus blood-screening products and strong partnership with Novartis provide an attractive market, with a global reach and significant growth opportunities for the combined company.According to Kalorama Information's last molecular diagnostic report, Gen-Probe was the third-largest competitor in molecular diagnostics, while Hologic had been (as of 2010) in eleventh place.
