Abcam’s Factor IX in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Human protein in human serum and plasma samples.
The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.
Factor IX, also known as Christmas Factor, is a 52 kDa zymogen of plasma serine proteases that initiates coagulation through activation by Tissue Factor (TF) and Factor VIIa. The activated form of Factor IX, known as Factor IXa, further activates an intrinsic activation complex that consists of factor X and factor VIIIa in the presence of Ca (2+) ions, and phospholipids. Mutations that cause a deficiency in Factor IX lead to x-linked hemophilia B, whereas overproduction of Factor IX has been shown to be a risk factor in venous thromboembolism (VTE). In 2013 the Food and Drug Administration approved the use of recombinant factor IX as a prophylactic treatment of patients with hemophilia B.
