Human monocyte serine esterase 1 (HMSE1) is an esterase isoenzyme expressed in monocyte/macrophages that can be inhibited by NaF in α-naphthyl acetate cytochemical staining applications. Intensive analysis of normal and malignant hematopoietic cells and leukemia-lymphoma cell lines using isoelectric focusing established the specificity of this enzyme for monocytes and related cells, hence its designation as monocyte-specific esterase. Monocyte-specific (carboxyl)esterase (MSE) is a marker enzyme which is well-known to hematologists as its detection is part of the traditional cytochemical stainings of monocyte lineage leukemia cells.

Synthetic peptide directed towards the N terminal region of human CES1

Anti-CES1 (AB1) polyclonal antibody is used to tag monocyte serine esterase 1 proteins for detection and quantitation by Western blotting and in cells and tissues by immunohistochemical (IHC) techniques. It is used as a probe to study the role of monocyte serine esterase 1 in monocytes and monocyte lineage leukemia.

Anti-CES1 (AB1) polyclonal antibody reacts with bovine, canine, rabbit, pig, human, mouse, and rat monocyte serine esterase 1 (MSE1) proteins.

CES1 is one of the enzymes responsible for the hydrolysis of ester- and amide-bond-containing drugs such as cocaine and heroin. They also hydrolize long-chain fatty acid esters and thioesters. This enzyme is known to hydrolyze aromatic and aliphatic esters and is necessary for cellular cholesterol esterification. It may also play a role in detoxification in the lung and/or protection of the central nervous system from ester or amide compounds. Carboxylesterase deficiency may be associated with non-Hodgkin lymphoma or B-cell lymphocytic leukemia.Carboxylesterase 1 is a member of a large multigene family.

It may also play a role in detoxification in the lung and/or protection of the central nervous system from ester or amide compounds. Carboxylesterase deficiency may be associated with non-Hodgkin lymphoma or B-cell lymphocytic leukemia. Three transcript variants encoding three different isoforms have been found for this gene.Carboxylesterase 1 is a member of a large multigene family.
