CD235a (Glycophorin A) Monoclonal Antibody (HIR2 (GA-R2)), eFluor™ 450, eBioscience™, Invitrogen™

Description

Description: The HIR2 monoclonal antibody reacts with human glycophorin A, a sialoglycoprotein expressed by erythroid precursors and mature circulating red cells. Applications Reported: This HIR2 (also GA-R2) antibody has been reported for use in flow cytometric analysis. Applications Tested: This HIR2 (also GA-R2) antibody has been pre-titrated and tested by flow cytometric analysis of diluted normal human peripheral blood cells. Binding of this antibody to red cells at high antibody concentration causes cell agglutination. This can be used at 5 μL (0.03 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.

Glycophorins A (GPA) and B (GPB) which are single pass membrane sialoglycoproteins. GPA is the carrier of blood group M and N specificities, while GPB accounts for S and U specificities. GPA and GPB provide the cells with a large mucin like surface and it has been suggested this provides a barrier to cell fusion, so minimizing aggregation between red blood cells in the circulation.
