CYP450-GP began operations in 2013, and focuses primarily on the production and distribution of specific inhibitory antibodies to human cytochrome P450 enzymes as well as the corresponding purified native and recombinant P450 immunogens. Prior to our founding, we had been acutely aware of the lack of specific probes to accurately distinguish cytochrome P450 enzyme catalysts in liver microsomes, and devoted extensive research efforts over the previous 15 or so years into developing such probes. In fact, you may have already utilized our human cytochrome P450 antibodies if these reagents were purchased from companies such as Research Diagnostics Inc., Fitzgerald Industries International or Abcam. After subsequently branching out on our own, we now provide these same antibodies and purified cytochrome P450 enzymes and other microsomal enzymes directly as a tool set for studying the metabolism of established drugs and NMEs in vitro.

CYP450-GP’s monospecific, inhibitory cytochrome P450 antibodies are robust probes for use in cytochrome P450 metabolism phenotyping experiments and are, in fact, are interchangeable with chemical inhibitors according to the FDA and EMA guideline. We now offer a kit (CYP Immunoinhibition Kit®) comprised of antibodies to the six most common cytochrome P450 drug-metabolizing enzymes to enable the researcher to easily and accurately identify the cytochrome P450(s) underlying oxidative metabolism of a given NME or other xenobiotic. Our purified cytochrome P450 monoxgenase enzymes can, upon reconstitution, be utilized to substantiate the data obtained with the cognate antibodies and intact liver microsomes.
