Liver microsomes con­tain cytochromes P450, flavin-monooxygenases, carboxyl­esterases, epoxide hydrolase, UDP-glu­cur­ono­syl­transferases and other drug-metabolizing enzymes, and are intended for use in in vitro studies of xenobiotic metabolism.

The S9 fraction is a mixture of microsomes and cytosol. Accordingly, it contains a wide variety of Phase 1 and Phase 2 enzymes including P450 enzymes, flavin-mono­oxygenases, carboxyl­esterases, epoxide hydrolase, UDP-glucuronosyl­transferases, sulfotransferases, methyl­transferases, acetyl­trans­ferases, gluta­thione S-trans­fer­ases and other drug-metabolizing enzymes.

Liver cytosol contains many xenobiotic metabolizing enzymes including carboxylesterases, soluble epoxide hydrolases, alcohol dehydrogenases, aldehydes oxidases, xanthine oxidases, diamine oxidases, sulfotransferases, glutathione S-transferases, etc.

Product Details

NOMENCLATURE Crl:(WI)BR ORIGIN To Scientific Products Farm, Ltd. [predecessor of Charles River United Kingdom (CRUK)] in 1947 from Wistar Institute. To CRL in 1975 from CRUK. Caesarean rederived in 1975 to form the nucleus of the current Wistar rat colonies. This particular colony was selected because of a low incidence of hydronephrosis. COAT COLOR Albino.
