* Cellomics Inc., of Pittsburgh, and Carl Zeiss, of Jena, Germany, signed a worldwide agreement to combine Zeiss' ultra-high throughput screening systems with Cellomics' technology, including high-content screening systems (HCS) for lead optimization and target information. The deal is an exclusive worldwide co-marketing, manufacturing, sales and support agreement. According to the companies, Cellomics' HCS system "allows the fully automated quantification of temporal and spatial activity of targets and cellular processes using multicolor fluorescence in analyses in living cells." The companies expect the initial deliveries of the fully integrated UHTS and HCS systems at the beginning of 1999.

* Immune Response Corp., of Carlsbad, Calif., released preclinical data showing its IR8101 induced strong gamma interferon and IgG2A antibody responses in mice. Similar responses, called a cell-mediated time immune response, have been found in animals and humans who have been exposed to the HIV virus but remain protected. The vaccine consists of gp120-depleted whole-killed HIV-1 antigens.

* Molecular Applications Corp., of Palo Alto, Calif., completed a $9.5 million round of equity funding.
