Echistatin (TFA)

Echistatin TFA, the smallest active RGD protein belonging to the family of disintegrins that are derived from snake venoms, is a potent inhibitor of platelet aggregation. Echistatin is a potent inhibitor of bone resorption in culture. Echistatin is a potent antagonist of αIIbβ3, αvβ3 and α5β1[1][2][3][4].
