Data Examples

Western Blot Detection of Human, Mouse, and Rat Carboxylesterase 1/CES1 by Western Blot. View Larger

Detection of Human, Mouse, and Rat Carboxylesterase 1/CES1 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, human liver tissue, mouse liver tissue, and rat liver tissue. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human/Mouse/Rat Carboxylesterase 1/CES1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4920) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Carboxylesterase 1/CES1 at approximately 63 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Carboxylesterase 1/CES1

Carboxylesterase 1 (CES1) is a member of a large family of carboxylesterases that are responsible for the hydrolysis of ester and amide bonds (1, 2). They have broad substrate specificity ranging from small molecule esters such as phenylester to long chain fatty acid esters and thioesters. They play a major role as determinants of pharmacokinetic behavior for most therapeutic agents containing an ester. By de-esterification, they can activate or inactivate the agents. They also participate in detoxification of drugs such as cocaine and heroin in serum and liver. The resulting de-esterified metabolites are secreted out in urine. They can also detoxify organophosphate and carbamate analogues used in agrochemicals or chemical nerve agents, such as malathion, sarin, tabun, and VX. In addition to the hydrolytic activity, they can perform transesterification, a reaction important for cholesterol homeostasis. Carboxylesterase deficiency may be associated with non-Hodgkin lymphoma or B-cell lymphocytic leukemia. CES1 shares the serine hydrolase fold observed in other esterases (3). CES1 possesses an endoplasmic reticulum retention signal (HIEL) at its C-terminus.
