General description
Band 3 is a hydrophobic protein, it exists in erythrocytes as a dimer and tetramer and has a strong tendency to aggregate because of oxidative stress.
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.

Specificity
The antibody recognizes an epitope located in the cytoplasmic N-terminus of the band 3 molecule/proteins (90-100kDa).
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-Human Band 3 has been used in immunoblotting. It may also be used in the study of red cell structures and functions and to study the fragmentation of the cytoplasmic domain of band 3 protein in vivo and in vitro.
Monoclonal anti-Band 3 antibodies can be used in ELISA and immunoprecipitation. It may also be used for immunofluorescent staining.
Biochem/physiol Actions
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).

In erythrocytes, the regulation of the redox sensitive Tyr phosphorylation of band 3 and its functions are still partially defined. A role of band 3 oxidation in regulating its own phosphorylation has been previously suggested. The current study provides evidences
