Product overview

Abcam’s Thromboxane B2 (TXB2in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Thromboxane B2 in biological fluids.

A goat anti-rabbit IgG antibody has been precoated onto 96-well plates. Standards or test samples are added to the wells, along with an alkaline phosphatase (AP) conjugated-TXB2 antigen and a rabbit polyclonal antibody specific to TXB2. After incubation the excess reagents are washed away and pNpp substrate is added. After a short incubation the enzyme reaction is stopped and a yellow color is generated. The intensity of the yellow coloration is inversely proportional to the amount of TXB2 captured in the plate.


Thromboxane A2 (TXA2) is involved in platelet aggregation, vasoconstriction and reproductive functions, but has a half life of only 37 seconds under physiological conditions. Thromboxane B2 (TXB2) is the stable product of the non-enzymatic hydration of TXA2, thus the production of TXA2 in vivo is typically monitored by measurement of TXB2 and its metabolite 2,3-dinor TXB2. 11-dehydro-TXB2 is a major metabolite of Thromboxane B2 (TXB2) found in urine and plasma produced by its dehydrogenation by the enzyme 11-OH-dehydrogenase.
