Description

Mouse Monoclonal Antibody

This antibody recognizes an epitope between amino acids 27 and 40 of the extracellular portion of CD235a (glycophorin A), a sialoglycoprotein expressed on early erythroblasts, late erythroblasts, erythroblasts, mature erythrocytes and the cells of erythroid cell lines K562 and HEL. The antibody does not react with glycophorin B.

Glycophorin A, also known as CD235a, is a 151 amino acid sialoglycoprotein expressed on the membrane of mature erythrocytes and erythroid progenitor cells, with approximately 500,000 copies per cell. The gene for glycophorin A is located on chromosome 4 and exists in two allelic forms, M and N, which differ by two amino acids: the M group has Ser1 and Gly5, while the N group has Leu1 and Glu5. These allelic variations define the blood group M and N specificities. Glycophorin A serves multiple functions, including providing a mucin-like barrier that minimizes aggregation between red blood cells in circulation, potentially preventing cell fusion. It also acts as a receptor for certain pathogens, including Sandei virus, parvovirus, and Hsa, a Streptococcus adhesin. Recent studies suggest that exposure to toxins can lead to mutations or loss of alleles, resulting in phenotypic changes. There is ongoing research correlating genotype and phenotype with predisposition to diseases such as cancer and heart disease, highlighting the importance of glycophorin A in both health and disease. Glycophorin A is a significant marker for studying erythrocyte-related functions and pathologies, as well as its role in pathogen interactions and disease predisposition.
