General description

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This antibody is Preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency". Click here for more information.
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 2B19 is a Rabbit recombinant monoclonal antibody that specifically detects COX-2. It targets an epitope within 22 amino acids from the C-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 22 amino acids from the C-terminal region of human Cyclooxygenase-2 (COX-2).

Application

Quality Control Testing

Evaluated by Western Blotting in A549 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected COX2 in A549 cell lysate.

Tested applications

Affinity Binding Assay: A representative lot of this antibody bound COX2 with a KD of 1.3 x 10-8 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected COX2 in human kidney tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected COX2 in A549 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-COX2, clone 2B19 ZooMAb®, Cat. No. ZRB1514, is a recombinant Rabbit monoclonal antibody that specifically targets COX2 and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Prostaglandin G/H synthase 2 (UniProt: P35354; also known as EC:1.14.99.1, Cyclooxygenase-2, COX-2, PHS II, Prostaglandin H2 synthase 2, PGH synthase 2, PGHS-2, Prostaglandin-endoperoxide synthase 2) is encoded by the PTGS2 (also known as COX2) gene (Gene ID: 5743) in human. COX2 is a peripheral membrane protein that is synthesized with a signal peptide (aa 1-17), which is subsequently cleaved off to generate the mature form that is detected on the lumenal side of the endoplasmic reticulum and nuclear envelope. It is an inducible enzyme and is generally present at very low levels in most tissues and its expression increases with cytokines and growth factor treatment. It is present mainly at inflammatory sites where it produces prostaglandins, which mediate inflammation, pain, and fever. COX2 displays cyclooxygenase and peroxidase activity in the biosynthesis pathway of prostanoid. Its cyclooxygenase activity oxygenates arachidonate to the hydroperoxy endoperoxide prostaglandin G2 (PGG2), and the peroxidase activity reduces PGG2 to the hydroxy endoperoxide PGH2, the precursor of all 2-series prostaglandins and thromboxanes. It also catalyzes successive cyclooxygenation and peroxidation of dihomo-g-linoleate and eicosapentaenoate to corresponding PGH1 and PGH3, the precursors of 1- and 3-series prostaglandins. It is also shown to metabolize 2-arachidonoyl glycerol yielding the glyceryl ester of PGH2, a process that can contribute to pain response. In vascular endothelial cells, it converts docosapentaenoate (DPA) to 13R-HDPA that activates macrophage phagocytosis during bacterial infection. COX2 activity can be inhibited by nonsteroidal anti-inflammatory drugs. 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 with 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.
