Product overview:
KE00034 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The F12 ELISA kit is to be used to detect and quantify protein levels of endogenous F12. The assay recognizes human F12. A polyclonal antibody specific for F12 has been pre-coated onto the microwells. The F12 protein in samples is captured by the coated antibody after incubation. Following extensive washing, a monoclonal antibody specific for F12 is added to detect the captured F12 protein. For signal development, horseradish peroxidase (HRP)-conjugated Anti-mouse antibody is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450nm.


Storage Instructions:
All the reagents are stored at 2-8℃. Refer to the protocol for further storage instructions.

Coagulation factor XII, F12, HAE3, HAEX, HAF, Hageman factor

Factor XII (FXII, Hageman factor) is a 80kD, single chain glycoprotein that circulates in blood as an inactive zymogen. FXII plays an important role in blood coagulation, fibrinolysis, and kinin generation. When plasma comes into contact with negatively charged surfaces such as glass, kaolin, or dextran sulfate, FXII is bound to the surface and undergoes limited proteolysis by plasma kallikrein, resulting in two active enzyme forms, ɑ-FXIIa and β-FXIIa. Hereditary deficiencies in FXII are not associated with spontaneous or excessive bleeding. FXII inhibition also have protective role against arterial thrombosis and stroke, suggesting that FXII may be a target for antithrombotic therapy. This kit is used to quantify FXII in vivo.
