Dual cyclooxygenase and peroxidase in the biosynthesis pathway of prostanoids, a class of C20 oxylipins mainly derived from arachidonate, with a particular role in the inflammatory response. The cyclooxygenase activity oxygenates arachidonate (AA, C20:4(n-6)) 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. This complex transformation is initiated by abstraction of hydrogen at carbon 13 (with S-stereochemistry), followed by insertion of molecular O2 to form the endoperoxide bridge between carbon 9 and 11 that defines prostaglandins. The insertion of a second molecule of O2 (bis-oxygenase activity) yields a hydroperoxy group in PGG2 that is then reduced to PGH2 by two electrons (PubMed:7947975). Involved in the constitutive production of prostanoids in particular in the stomach and platelets. In gastric epithelial cells, it is a key step in the generation of prostaglandins, such as prostaglandin E2 (PGE2), which plays an important role in cytoprotection. In platelets, it is involved in the generation of thromboxane A2 (TXA2), which promotes platelet activation and aggregation, vasoconstriction and proliferation of vascular smooth muscle cells (Probable).

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
COX-1 is involved in producing prostaglandins that regulate a variety of normal physiological processes including gastric mucosal protection renal blood flow and platelet aggregation. Unlike COX-2 COX-1 is not induced by inflammatory stimuli and is not part of an inducible complex. It serves to maintain essential physiological functions in various organs and systems making its activity critical for cellular maintenance.
Cyclooxygenase 1 (COX-1) also known as COX1 cyclooxygenase-1 COX one and the COX1 protein is an important enzyme in the conversion of arachidonic acid to prostaglandins. It is a heme-containing dimer enzyme with a molecular weight of approximately 70 kDa. COX-1 is widely expressed in most tissues and cell types where it plays a significant role in maintaining homeostatic functions. This protein is constitutively active meaning it is often active under normal physiological conditions.
COX-1 is primarily involved in the prostaglandin biosynthesis pathway. It converts arachidonic acid into prostaglandin H2 a precursor for other prostaglandins and thromboxanes. Thromboxane A2 produced from this pathway plays an important role in platelet aggregation and vasoconstriction linking COX-1's functions with hemostatic processes. Another protein involved in this pathway is thromboxane synthase which further processes the products of COX-1 activity.
COX-1’s role connects it closely to conditions like peptic ulcers and cardiovascular diseases. Inhibition of COX-1 by nonsteroidal anti-inflammatory drugs (NSAIDs) can lead to gastric mucosal damage contributing to the development of peptic ulcers. Additionally due to its involvement in platelet aggregation COX-1 affects thrombotic diseases. COX-1's interactions with proteins such as COX-2 become relevant in inflammation and pain management where selective inhibition of COX-2 is sought to reduce adverse effects related to COX-1.
