CD41a Monoclonal Antibody (HIP8), eFluor™ 450, eBioscience™, Invitrogen™

Description

Description: The HIP8 monoclonal antibody reacts with the human CD41 molecule, the integrin alpha IIb also known as platelet GPIIb. CD41 non-covalently associates with integrin beta3 (GPIIIa, CD61) and is expressed by megakaryocytes and platelets. The CD41/CD61 complex is a receptor for fibronectin, fibrinogen, von Willebrand factor, vitronectin and thrombospondin and mediates platelets aggregation. HIP8 blocks platelet aggregation. Applications Reported: This HIP8 antibody has been reported for use in flow cytometric analysis. Applications Tested: This HIP8 antibody has been pre-titrated and tested by flow cytometric analysis of human platelets. This can be used at 5 μL (0.5 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. eFluor™ 450 is an alternative to Pacific Blue™. eFluor™ 450 emits at 445 nm and is excited with the Violet laser (405 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser. Filtration: 0.2 μm post-manufacturing filtered.

CD41 (platelet glycoprotein IIb, ITGA2B) is composed of two subunits -120 kDa a, alpha and 23 kDa b, beta- that interact with CD61 in the presence of calcium to form a functional adhesive protein receptor. CD41 is also involved in blood coagulation by mediating platelet aggregation. Upon blood vessel damage, CD41 binds to a variety of proteins including von Willebrand factor, fibrinogen, fibronectin and vitronectin. CD41 is mainly expressed on megakaryocyte-platelet lineage, but generally belongs to the antigens that are expressed during the early stages of hematopoietic differentiation. Diseases associated with CD41 dysfunction include Glansmann Thrombasthenia, and Platelet type-16 bleeding disorder.
