Thromboxane A2 (TXA2) is produced from arachidonic acid (Item No. 90010) by many cells and causes irreversible platelet aggregation and contraction of vascular and bronchial smooth muscle.1,2,3 TXA2 is rapidly hydrolyzed non-enzymatically to TXB2 (Item No. 19030), which is then quickly metabolized to urinary metabolites for clearance by the kidneys. TXB2-biotin is an affinity probe which allows TXB2 to be detected through an interaction with the biotin ligand. It was designed to allow TXB2 to be detected in complexes with protein binding partners.
