Invitrogen™ CD41a Monoclonal Antibody (eBioMWReg30 (MWReg30)), FITC, eBioscience™, Invitrogen™

Beschreibung

Description: The eBioMWReg30 monoclonal antibody reacts with mouse CD41 (fibrinogen receptor, gpIIb, integrin alpha Iib). While initially thought to be expressed exclusively on the surface of platelets and megakaryocytes, it has been demonstrated that CD41 is also expressed on hematopoietic progenitors in the embryo, fetus and adult. CD41 associates with CD61 (gpIIIa, integrin beta III) to form a receptor which plays a major role in platelet function, including binding of several adhesion molecules such as fibrinogen, fibronectin and vitronectin. Recently, the SLAM-family markers, CD48 and CD150 have been used to reliably identify hematopoietic stem cells (HSC). Specifically, it was found that CD150+CD48- bone marrow cells were highly efficient in their ability to confer long-term multi-lineage reconstitution in irradiated mice. Furthermore, the efficiency of reconstitution was enhanced when HSCs were further enriched through the exclusion of CD41+ cells. Thus, the use of CD150+CD48-CD41- as an expression profile efficiently identifies hematopoietic stem cells. Applications Reported: This eBioMWReg30 (MWReg30) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioMWReg30 (MWReg30) antibody has been tested by flow cytometric analysis of mouse platelets. This can be used at less than or equal to 0.125 μg per test.

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.
