Invitrogen™ CD42b Monoclonal Antibody (AK2)

Mouse Monoclonal Antibody

Supplier:  Invitrogen™ MA544051

Catalog No. PIMA544051

Description

This antibody recognizes an extracellular epitope of CD42b (GPIb alpha), a 135-145 kDa membrane glycoprotein expressed on platelets and megakaryocytes. CD42b and CD42c (GPIb beta) are composed in a disulfide linked heterodimer (CD42b/c; 160 kDa); CD42b/c forms a noncovalent complex with CD42a and CD42d.

CD42b is a platelet activation marker involved in the process of coagulation as an aggregating factor. It interacts with extracellular matrix as well as with adhesion molecules. CD42b expression and activation seems to be regulated by VEGF and PDGF. CD42b composes together with GPIb beta, GPIX and GPV the GPIb-IX-V receptor complex critical in the process of platelet-rich thrombus formation by tethering the platelet to a thrombogenic surface. CD42b binds to von Willebrand factor (VWF) exposed at a site of vascular injury, as well as to thrombin, coagulation factors XI and XII, high molecular wight kininogen, TSP-1, integrin Mac-1 and P-selectin. The extracellular domain of CD42b by its interactions also contributes to metastasis. Further, CD42b antigen is expressed on platelets and on megakaryocytes in bone marrow. Several polymorphisms and mutations have been described in the CD42b, some of which are the cause of Bernard-Soulier syndromes and platelet-type von Willebrand disease.
