Rat F7(Coagulation Factor VII) ELISA Kit

Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa also converts factor IX to factor IXa in the presence of tissue factor and calcium (By similarity) Assay Type: Sandwich. Sensitivity: 12.4 pg/mL. Standard: 1000 ng/mL. Detection range: 15.63-1000 ng/mL. Sample type: Plasma. Assay length: 3.5h. Research Field: Metabolic pathway,Infection immunity,Hematology,. Test principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat F7. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat F7. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat F7, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat F7 in the samples is then determined by comparing the OD of the samples to the standard curve.
