Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate TXA2 in samples. An antibody specific for TXA2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTXA2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TXA2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TXA2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Thromboxane B2 is a metabolite of thromboxane A2 which is known to be highly unstable under physiological conditions. Thromboxane B2 is recognized as a valuable substance for study of a variety of biochemical processes as well as important synthetic precursor to thromboxane A2.Several syntheses of thromboxane B2 have been completed, either in racemic form or deriving the stereocenters from a chiral pool. The Burke group is currently endeavoring to complete the total synthesis of thromboxane B2. Thromboxane B2 is an inactive metabolite/product of thromboxane A2. It is almost completely cleared in the urine.It itself is not involved in platelet activation and aggregation in case of a wound, but its precursor, thromboxane A2, is. Thromboxane A2 synthesis is the target of the drug aspirin, which inhibits the COX-1 enzyme (the source of thromboxane A2 in platelets).
