This panel of human and rodent cytochrome P450 (CYP450) antibodies, is for use in drug discovery programs and play an essential role in drug metabolism in the liver. Understanding drug metabolism is critical in designing more sensitive, and ultimately more predictive, assays for estimating possible liver toxicity. These antibodies bind to most human isoforms of CYP450, as well as rat and mouse isoforms. They will be used to develop novel assays for the pharmaceutical, cosmetic, agricultural and industrial sectors. Millipore Corp., 800-548-7853, www.millipore.com.
