ANTI-HUMAN CD42B

Uses

The reagent is designed for Flow Cytometry analysis. Suggested working dilution for Flow Cytometry is 2-8 μg/mL of sample. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.

General Description

The mouse monoclonal antibody AK2 recognizes 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.

Biochem/physiol Actions

Cluster of differentiation 42b (CD42b) clustering promotes integrin αIIbβ3-dependent platelet aggregation, phagocytosis and rapid platelet clearance in the liver. The encoded protein acts as a platelet receptor for von Willebrand factor (VWF) and other ligands present in circulation. Mutation in the gene leads to autosomal recessive Bernard-Soulier syndrome. CD42b interacts with plasma hemoglobin (Hb) and enhances platelet activation and apoptosis in a concentration-dependent manner and also regulates platelet functions.
