Datasheet of S-2765(FXa substrate)
Description: S-2765, which is specific to activated factor X (FXa), is a short peptide covalently bound to pNA (4-nitroaniline). When attacked by FXa, it releases a free pNA which could be detected by a spectrophotometer at 405 nm.S-2765 is mainly used in anti-FXa activity assay of heparin. S-2765 can be used in many applications, such as: 1:Anti-factor Xa activity to anti-factor IIa activity ratios of heparin and LMWHs. 2: Anti-factor Xa activities of heparin and LMWHs. 3: Activities of antithrombin and coagulation factors. 4: Anti-factor Xa activities of heparin and LMWHs in human plasma. 5: Production of kits for automated blood analyzers. 6: Evaluation of potential anticoagulants from chemical synthesis, bacterial fermentation and animal tissues.
