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:CD (SD)IGS BR ORIGIN Originated in 1925 by Robert W. Dawley from a hybrid hooded male and a female Wistar rat. To CRL in 1950 from Sprague Dawley, Inc. Caesarean rederived in 1955 from original Charles River Sprague Dawley® colonies. In 1991, 8 colonies were selected to form the IGS Foundation Colony. Rederived into isolator foundation colony in 1997. IGS refers to animals bred using the CRL International Genetic Standard system. COAT COLOR Albino.
