产品简介 (Background) |
Beyotime's recombinant human active form of human COX1 (rhCOX1) was expressed in HEK293 cells and purified, which contains the full length of COX1 (24-599aa) with a His tag (8X His) and a Twin-Strep tag (SAWSHPQFEKGGGSGGGSGGSAWSHPQFEK) at the C-terminus. Cyclooxygenase is a bifunctional enzyme that first catalyzes the addition of two moles of molecular oxygen to arachidonic acid to form the hydroperoxide PGG2, then reduces the hydroperoxide to the alcohol, PGH2, by a peroxidase activity. Cyclooxygenase is found in two forms: COX1, which is constitutively expressed in most cells, is responsible for the production of prostaglandins that maintain homeostasis; and COX2, which is upregulated in inflammatory cells in response to an inflammatory stimulus (cytokines, LPS, etc.), is responsible for the production of prostaglandins at the site of inflammation [1]. |
产品用途 (Applications) |
Active human COX1 is useful in studying enzyme regulation, determining target substrates, screening COX1 inhibitors or as a positive control in COX1 activity assays. |
