Specificity
By immunoblotting, the antibody localizes specifically the α, αδ, α2 bands in extracts of human red blood cell ghosts. The antibody (also cited as clone no. 15D4) binds to 8% of bone marrow nucleated cells in smears and tissue preparations using immunofluorescent microscopy or flow cytometry.
Immunogen
human thymus
Application
Monoclonal Anti-Glycophorin A (α) antibody produced in mouse is suitable for:
- agglutination assay at a working dilution of 1:800 using human erythrocytes
- flow cytometry using bone marrow nucleated cells
- indirect immunofluorescence using bone marrow nucleated cells
- western blot using extracts of human red blood cell ghosts
Biochem/physiol Actions
Glycophorins (GP) are sialic acid-rich polypeptides (sialoglycoproteins) that are part of the erythrocyte membrane. They are denoted α, β, γ, δ based on the decreasing molar mass. GPA and GPB are the major constituents of the red cells. They may be present as single polypeptides (α and δ), as stable homodimers (α2 and δ2) and heterodimers (αδ). Depending upon the amino acid residues at positions 1 and 5, GPA carries blood group M or N. GPA is associated exclusively with erythroid cells. It is expressed in pronormoblasts and later erythroid cells. GPA has a cytoplasmic domain that interacts with cytoskeletal structure upon induction by binding to ligand. This interaction improves RBC membrane rigidity and reduces deformability.

Erythrocyte skeletal proteins are known to play an important role in determining membrane deformability. In order to see whether transmembrane proteins also influence deformability and, if so, whether this influence is mediated by an interaction with the membrane skeleton, we

The surface of the human red blood cell is dominated by a small number of abundant blood group active proteins. The major proteins are the anion transport protein (band 3) which has AB(H) activity, and Glycophorin A which has MN

The minor red cell sialoglycoproteins--beta and gamma (also known as glycophorin C)--are believed to be important to the structural integrity of red cells. The absence of sialoglycoproteins alpha and delta, as seen in En(a-) and S-s-U- cells, respectively, results in

Acute, inflammatory conditions associated with dysregulated complement activation are characterized by significant increases in blood concentration of reactive oxygen species (ROS) and ATP. The mechanisms by which these molecules arise are not fully understood. In this study, using luminometric- and
