General Description of Cyclooxygenase-2 .
This antibody reacts with a 70 kDa protein. COX-2 (Cyclooxygenase-2) is an inducible enzyme. It is involved in the response of cells to growth factors, tumor promoters and cytokines that induce its expression. COX-2 expression markedly increased in 85-90% of human colorectal adenocarcinoma whereas COX-1 levels remained unchanged.

Antibody (Suitable for clinical applications)

Sample Type: FFPE Patient Samples.
Tested Applications: IHC. Approved for In Vitro Diagnostic Procedures on FFPE tissues. For tissue collection recommendations, please see datasheet sent with product.

Cyclooxygenase-2 Information for Pathologists


Not related to Cytochrome c oxidase (COX). Cyclooxygenases 1 (COX1) and 2 (COX2), also known as prostaglandin H synthase, catalyze formation of prostaglandin from arachidonic acid. COX1 is constitutive form of enzyme on 9q; COX2 is inducible isoform on 1q, has 61% sequence homology with COX1. Regulated by mitogens, tumor promoters, cytokines, serum, free fatty acids, NSAIDs, selective COX2 inhibitors. Increased expression associated with poor clinical outcome in stage I/II non-small cell lung carcinoma (Arch Pathol Lab Med 2005;129:1113), possibly poorer outcome in follicular thyroid carcinoma (Arch Pathol Lab Med 2005;129:736).

Common Uses By Pathologists:

Endothelial cells (cytoplasmic) as well as breast, colorectal, esophageal, liver, lung, ovary, pancreas, prostate, skin, stomach tumors stain positive for COX2.
