Description

Immunogen

Glycophorin B from human erythrocytes.

Application

Monoclonal Anti-Band 3 antibody can be used for western blot, immunoprecipitation and indirect immunofluorescence using human erythrocytes.

Monoclonal anti-Band 3 antibodies can be used in ELISA and immunoprecipitation. It may also be used for immunofluorescent staining.

General description

Band 3 is an anion exchanger that is abundantly found in erythrocyte membranes. This integral membrane anion exchanger protein regulates mechanical stability and ion homeostasis across the red blood cell membrane. Genetic alterations in Band 3 have been associated with familial distal renal tubular acidosis
Monoclonal Anti-Band 3 antibody detects Band 3 protein (90-100 kD) and several lower molecular mass peptides migrating in SDS-PAGE gels in the regions of 60, 40 and 20 kD. The product specifically binds to the cytoplasmic amino-terminal protein of band 3 (the epitope is approx. 20 kD from the N-terminal end). As the epitope is not located at the erythrocyte surface, the antibody product does not agglutinate red blood cells. Furthermore, its cell surface binding cannot be detected by an indirect agglutination assay. The antibody does not localize Band 3 from horse, bovine, pig, guinea pig, dog or mouse erythrocytes, nor does it localize Band 3 from nonerythroid human fibroblast extract.

Band 3, a 90-100kD protein is the major integral protein of human erythrocytes responsible for anion exchange. It also regulates the intracellular pH. Monoclonal anti-Band 3 antibody is useful in in vivo and in vitro study of fragmentation of cytoplasmic domain of band 3 protein. It may also be used for immunoblot analysis. Monoclonal Anti-Human Band 3 antibody reacts specifically with cytoplasmic N-terminal band 3 proteins (90-100kD).
