Carboxylesterase 1 Protein, Human (HEK293, His)

Carboxylesterase 1 Protein, Human (HEK293, His) is an approximately 60.0 kDa human carboxylesterase 1 protein with a His-flag. Human Carboxylesterase 1 is the key liver microsomal enzyme that takes part in detoxification and metabolism^[1]. 

Carboxylesterases are a family of enzymes that act on a variety of both exogenous (e.g. cocaine) and endogenous (e.g. acyl-CoA esters) substrates. Carboxylesterases are encoded by carboxylesterase (CES or Ces) genes^[1].
Carboxylesterase are defined to hydrolyze ester, amide, or thioester bonds to their corresponding alcohol, amine or thiol and free acid. Human Carboxylesterase 1 (hCES1) is the key liver microsomal enzyme responsible for detoxification and metabolism of a variety of agents^[1]. 

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
