Active Carboxylesterase 1 (CES1)
20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

Testing Data
(Carboxylesterase 1 (CES1) also known as liver carboxylesterase 1 is a serine esterase and member of a large multigene carboxylesterase family. The protein Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Thus, the recombinant mouse CES1 activity was measured by its ability to hydrolyze 4-Nitrophenyl acetate (4-NPA) to 4-Nitrophenol. The reaction was performed in 50mM Tris, pH 7.5 (Assay Buffer), ainitiated by addition 50L of various concentrations of CES1 (dilute by Assay Buffer) to 50uL of 2mM Substrate 4-NPA (100mM stock in Acetone, dilute by deionized water). Incubated at 37 for 10min, then read at a wavelength of 400nm. One unit of enzyme activity is defined as the 1g of enzyme required to convert 1pmol of 4-Nitrophenyl acetate to 4-Nitrophenol in 1min at 37 degree C. The specific activity of recombinant mouse CES1 is 1648 pmol/min/ug.Specific Activity (pmol/min/ug)= OD=Adjusted for Substrate BlankF=Conversion Factor(convert from standard curve of 4-Nitrophenol)T= TimeN=Amount of enzymeFigure.

Uniprot Description
CES1: Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Catalyzes the transesterification of cocaine to form cocaethylene. Displays fatty acid ethyl ester synthase activity, catalyzing the ethyl esterification of oleic acid to ethyloleate. Belongs to the type-B carboxylesterase/lipase family. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The CES1 ces1 (Catalog #AAA2122349) is an Active Protein and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is Gly31~Arg286. AAA Biotech's Carboxylesterase 1 can be used in a range of immunoassay formats including, but not limited to, Cell Culture, Activity Assays. Researchers should empirically determine the suitability of the CES1 ces1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Carboxylesterase 1, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
