IGS Sprague-Dawley Rat Kidney Subcellular Fractions
View ProductsDESCRIPTIONPACKAGINGCHARACTERIZATION PROVIDEDPRODUCT DETAILSRELATED PRODUCTSPRODUCTSDESCRIPTION
Drug-metabolizing enzymes in the kidney play a significant role in the metabolism of many xenobiotics. Kidneys have many metabolic responsibilities including the hydroxylation of fatty acids and their derivatives, which is one of the functions of the CYP4A and CYP4B enzymes expressed in renal microsomes. There is increasing interest in renal metabolism due to the significant role that kidneys play in the metabolism of drugs and the fact that the kidney is a major site of drug-induced toxicity.
To assess the stability of human and animal renal subcellular fractions, pooled samples were subjected to several freeze-thaw cycles, and analyzed for lauric acid 12-hydroxylation, umbelliferone glucuronidation and NADPH-cytochrome
c reduction. As shown below, renal samples prepared by XenoTech’s subcellular fractionation protocol can be repeatedly frozen and thawed at least ten times without significant loss of CYP4A activity. Similar results were obtained for umbelliferone glucuronidation and NADPH-cytochrome
c reduction.

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.
