Liver carboxylesterase 1 isoform a, CES1, ACAT, CE-1, CEH, CES2, hCE-1, HMSE, HMSE1, PCE-1, REH, SES1, TGH, Acyl-coenzyme A:cholesterol acyltransferase, Brain carboxylesterase hBr1.
CES1 is a part of the alpha/beta fold hydrolase familyand participates in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. CES1hydrolyzes aromatic and aliphatic esters, although it has no catalytic activity toward amides or a fatty acyl-CoA ester. CES1hydrolyzes the methyl ester group of cocaine to form benzoylecgonine and catalyzes the transesterification of cocaine to form cocaethylene. CES1also plays a role in detoxification in the lung and protection of the central nervous system from ester or amide compounds.CES1 is found in most tissues, mainly in the liver.
CES1 Human produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 559 amino acids (19-568 a.a.) and having a molecular mass of 61.7kDa (Molecular size on SDS-PAGE will appear at approximately 50-70kDa).
CES1 is expressed with a 9 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
CES1 protein solution (0.5mg/ml) contains 25mM Sodium Acetate (pH 4.0), 10% glycerol, 0.1M NaCl and 0.1mM PMSF.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
