Scientific Data

Western Blot Detection of Mouse and Rat Carboxylesterase 3/CES3 antibody by Western Blot. View Larger

Detection of Mouse and Rat Carboxylesterase 3/CES3 by Western Blot. Western blot shows lysates of mouse lung tissue and rat lung tissue. PVDF Membrane was probed with 1 µg/mL of Mouse Carboxylesterase 3/CES3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5985) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Carboxylesterase 3/CES3 at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Carboxylesterase 3/CES3

Carboxylesterase 3 is a member of a large family of carboxylesterases that are responsible for the hydrolysis of ester and amide bonds (1, 2). These carboxylesterases are widely distributed in mammalian tissues and have broad substrate specificity ranging from small molecule esters such as phenylester to long-chain fatty acid esters and thioesters. Because many ester-containing drugs require the ester linkage to improve the bioavailability of therapeutic agents, CESs play a major role in drug metabolism and activation. CES3 is also known as triacylglycerol hydrolase for its lipolytic activity. It has been reported to be the major lipase in white adipose tissue (3). Mouse CES3 shares 93% homology with rat CES3.
