anti- CD42b antibody

Background

Glycoprotein Ib platelet subunit alpha (GP1BA) is a critical component of the glycoprotein Ib-IX-V complex (GPIb-IX-V) on the surface of platelets. This complex plays a central role in the process of hemostasis, specifically in the adhesion of platelets to the damaged endothelium at sites of vascular injury. Hemostasis is crucial for preventing blood loss and initiating the wound healing process, and the proper functioning of the GPIb-IX-V complex is vital for platelet tethering under high shear stress conditions, such as in arterioles. GP1BA is the alpha subunit of GPIb, which is responsible for mediating the interaction with von Willebrand factor (vWF), a plasma glycoprotein that anchors platelets to the site of injury. Through its interactions with vWF, GP1BA enables the binding of platelets to exposed subendothelial matrix components, initiating platelet activation and aggregation.
