CD41a Monoclonal Antibody (HIP8), APC-eFluor™ 780, eBioscience™

Product Specific Information

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-diluted and tested by flow cytometric analysis of human platelets. This may be used at 5 µL (0.25 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.

APC-eFluor 780 emits at 780 nm and is excited with the Red laser (633-647 nm). Please make sure that your instrument is capable of detecting this fluorochrome.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222-49) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333-57) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 633-647 nm; Emission: 780 nm; Laser: Red Laser.

Target Information

CD41, also known as platelet glycoprotein IIb or ITGA2B, is a protein composed of two subunits: a 120 kDa alpha subunit and a 23 kDa beta subunit. It interacts with CD61 (gpIIIa, integrin beta III) in the presence of calcium to form a functional adhesive protein receptor. Initially thought to be expressed exclusively on platelets and megakaryocytes, CD41 is also found on hematopoietic progenitors in the embryo, fetus, and adult, indicating its role in early stages of hematopoietic differentiation. CD41 plays a crucial role in platelet function and blood coagulation by mediating platelet aggregation. Upon blood vessel damage, CD41 binds to various adhesion molecules, including von Willebrand factor, fibrinogen, fibronectin, and vitronectin, facilitating platelet adhesion and aggregation. This receptor is essential for platelet function, contributing to the binding of several adhesion molecules and playing a significant role in hemostasis. Diseases associated with CD41 dysfunction include Glanzmann Thrombasthenia and Platelet type-16 bleeding disorder, highlighting its importance in normal platelet function and blood coagulation processes.
