Related Product Information for TAFI Antigen elisa kit
The VisuLize TAFI Antigen ELISA Kit is an Enzyme Immunoassay for the quantitative determination of TAFI Antigen in human plasma samples using the double antibody enzyme linked immuno-sorbent assay (ELISA). This TAFI Antigen ELISA Kit is for Research Use Only and must not be used for test applications.
TAFI (Thrombin Activatable Fibrinolysis Inhibitor), also referred to as plasma procarboxypeptidase-B, procarboxypeptidase-U and R, circulates in plasma as a zymogen with a mass of 58,000 daltons. Proteolytic activation of TAFI yields an N-terminally derived activation peptide and the C-terminal portion corresponding to the metalloprotease, activated TAFI (TAFIa). TAFIa exhibits exopeptidase activity with carboxypeptidase B-like substrate specificity capable of catalyzing the hydrolysis of C-terminal lysine and arginine residues. Cleavage of these residues on fibrin by TAFIa attenuates clot lysis by inhibiting the formation of the ternary activation complex comprising fibrin cofactor, tPA and plasminogen, thereby inhibiting plasmin generation. Although TAFI can be activated by various proteases including thrombin and plasmin, the physiological activator is proposed to be the complex thrombin-thrombomodulin since the rate of activation is stimulated 1250-fold compared to thrombin alone¹. However, the rate of TAFI activation is highly dependent upon its plasma concentration. Since TAFIa apparently plays a key role in connecting coagulation and fibrinolysis and significantly increases clot stability, determination of plasma concentration of TAFI is likely crucial to assess its subsequent potential anti-fibrinolytic effects. This has been demonstrated in a report identifying high plasma concentration of TAFI as a risk factor for thrombosis

Product Notes
The Human TAFI Antigen (Catalog #AAA514071) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA514071 ELISA Kit recognizes Human TAFI Antigen. It is sometimes possible for the material contained within the vial of "TAFI Antigen, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
