The HY101 monoclonal antibody specifically binds to a collagen receptor, Platelet Glycoprotein VI (GPVI or GP6). GPVI is a 58-kD platelet membrane glycoprotein that belongs to the immunoglobulin superfamily. Upon blood vessel wall injury and consequent endothelial cell damage, platelets collect upon the exposed collagen fibers present in the subendothelial matrix. The platelet and collagen interaction leads to activated platelet aggregation and thrombus formation. Although normally serving a protective function in clot formation that limits blood loss, the platelet GPVI/collagen interaction may also play a role in myocardial infarction and stroke which are associated with the rupture of atherosclerotic plaques.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
