EBS-CD-034 reacts with a complex of CD41 and CD61, i.e. alpha IIb integrin and the integrin beta chain. The MW of the GPIIIa is 105 kDa unreduced and 90 kDa reduced. The integrin beta 3 chain can also form a complex called the vitronectin receptor with integrin alpha V: the CD51/CD61 complex. Ligands are fibrinogen, fibronectin, von Willebrand factor, vitronectin and thrombospondin. Residues 237-248 of GPIIIa or CD61 are critical in adhesive protein binding. The CD51/CD61 complex is also found on endothelial cells, some B-cells, monocytes/macrophages and tumor cells.
Positive control: U937, KG1a, HEL cells, human platelets in lymph nodes or tonsils.
