Product Information

Biological Activity	Measured by its ability to hydrolyze p-nitrophenylacetate. The specific activity is >10,000 pmol/min/μg.
Description	CES1 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 62.08 kDa and the accession number is NP_001020365.
Species	Human
Expression System	HEK293 Cells
Tag	C-His
Accession Number	P23141
Synonyms	TGH,SES1,REH,PCE-1,HMSE1,HMSE,hCE-1,CES2,CEH,CE-1,carboxylesterase 1,ACAT
Construction	A DNA sequence encoding the Human CES1 (NP_001020365) (Met1-Leu567) was expressed with a polyhistidine tag at the C-terminus. Predicted N terminal: Gly 18
Protein Purity	≥ 95 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.
Molecular Weight	62.08 kDa (predicted); 55.49 kDa (reducing conditions)
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
Research Background	CES1 encodes carboxylesterase-1, an important drug-metabolizing enzyme with high expression in the liver. Variants generated by the exchange of segments with CES1P1 complicate the genotyping of CES1. CES1 is involved in the hydrolysis of ester group-containing xenobiotic and endobiotic compounds including several essential and commonly used drugs. The individual variation in the efficacy and tolerability of many drugs metabolized by CES1 is considerable. However, it has been problematic to express recombinant CES1 in bacterial expression systems due to low solubility, with the CES1 protein being mainly expressed in inclusion bodies, accompanied by insufficient purity issues. CES1 is capable of catalyzing the hydrolysis of a wide range of therapeutic agents, toxins, and endogenous compounds. Accumulating studies have demonstrated associations between the expression and activity of CES1 and the pharmacokinetics and/or pharmacodynamics of CES1 substrate medications.
