CD41a antibodies, human

Clone: REA386 | Dilution: 1:11
Clone REA386 recognizes the human CD41a antigen, a calcium-dependent complex of CD41/CD61 (GPIIb/IIIa) expressed on normal platelets and megakaryocytes. The CD41/CD61 complex is a receptor for fibronectin, fibrinogen, von Willebrand factor, vitronectin, and thrombospondin and is required for platelet aggregation and clotting. Mutations of either CD41 or CD61 in humans causes Glanzmann’s thrombasthenia. Notably, CD41 is also the first blood-specific marker during
in vitro
differentiation of embryonic stem cells and is expressed on all hematopoietic stem and progenitor cells in the early embryo. However, CD41 expression is downregulated in midgestation embryos, and it is currently thought that CD41 expression on adult hematopoietic stem cells remains switched off throughout adult life.
Additional information: Clone REA386 displays negligible binding to Fc receptors.

Alternative Names

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the different hybridoma clones.
