• Specificity: Clone 1D4 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Liver carboxylesterase 1 (CES1). It targets an epitope within 14 amino acids from the C-terminal region.
• Immunogen: KLH-conjugated linear peptide corresponding to 14 amino acids from the C-terminal region of human Liver Carboxylesterase 1 (CES1).
• Application: Quality Control TestingEvaluated by Western Blotting in A549 cell lysate.Western Blotting Analysis: A 1:10,000 dilution of this antibody detected hCE-1/CES1 in A549 cell lysate.Tested ApplicationsWestern Blotting Analysis: A 1:1,000 dilution from a representative lot detected hCE-1/CES1 in Human liver, Mouse liver, and Rat liver tissue lysates.Western Blotting Analysis (WB): A 1:1,000 dilution of this antibody detected hCE-1/CES1 in THP-1 lysate from cells, but much reduced expression was observed in lysates from THP-1 cells with hCE-1/CES1 knockout.

• Target description: Liver carboxylesterase 1 (UniProt: P23141; also known as EC: 3.1.1.13, Acyl-coenzyme A:cholesterol acyltransferase, ACAT, Brain carboxylesterase hBr1, Carboxylesterase 1, CE-1, hCE-1, Cocaine carboxylesterase, Egasyn, HMSE, Monocyte/macrophage serine esterase, Retinyl ester hydrolase, REH, Serine esterase 1, Triacylglycerol hydrolase, TGH) is encoded by the CES1 (also known as CES2, SES1) gene (Gene ID: 1066) in human. hCE-1/CES1 is a member of the serine hydrolase superfamily that is localized within the lumen of the endoplasmic reticulum in many tissues. It is synthesized with a signal peptide (aa 1-17), which is subsequently cleaved off to produce the mature enzyme. This cleavage can occur at 2 positions, either between Trp-17 and Gly-18 or between Gly-18 and His-19. It is highly expressed in the liver but can be found to a lesser extent in the intestine, macrophages, and other tissues. It catalyzes the ester cleavage of a large number of structurally diverse ester- or amide-containing substrates into the corresponding alcohol and carboxylic acid. It is involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs.  It also possesses triglyceride and cholesterol ester hydrolase activity and may play an important role in regulating lipid metabolism.  It hydrolyzes cellular cholesteryl esters to free cholesterols and promotes reverse cholesterol transport by facilitating both the initial and final steps in the process. It allows free cholesterol efflux from macrophages to extracellular cholesterol acceptors and then releases free cholesterol from lipoprotein-delivered cholesteryl esters in the liver for bile acid synthesis or direct secretion into the bile. hCE-1/CES1 can exist either in a homotrimeric or a homohexameric form. Three isoforms of hCE-1/CES1 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity™, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
• Reconstitution: 300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
• Storage and Stability: Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
