Polyclonal Rabbit Affinity Purified E B
Anion exchangers (AE) are membranes proteins involved in the regulation of intracellular pH, cell volume regulation as well as in transepithelial acid/base transport. AE proteins are sodium-independent exchangers that mediates one-for-one exchange of extracellular Cl- for intracellular HCO3- ions resulting in intracellular acidification. AE proteins are encoded by a family of at least three related genes (AE1, AE2 and AE3). Numerous alternatively spliced isoforms of each AE gene are expressed in various tissues. AE proteins are exemplified by a large N-terminal cytoplasmic domain (~40-75kD) that provides binding sites for cytoskeleton protein, glycolytic enzymes and hemoglobin. The N-terminal cytoplasmic domains of AE2 are AE3 are more closely related than AE1. In fact, AE1 N-terminus is 300aa shorter than both the AE2 and AE3. The C-terminal TM domain (~55kD) is highly conserved (~70% identity) among various AE, spans the lipid bilayer 12-14 times. It is able to mediate anion exchange by itself. AE1 protein (also know as band 3) is the most abundant protein in red cell membrane. AE1 gene has been cloned and characterized from a variety of species including mouse, rat, human and chicken.
Catalog #A2295-13A
Recommended DilutionWestern Blot: 1-10ug/ml (ECL.) AE1 has a molecular weight of ~90-100kD. It aggregates easily forming dimers and multimers. It may also be proteolytically processed to smaller fragments of 60, 40 and 20kD.
ELISA: 1-10ug/ml. Using 1ug/ml A2295-13B4 control peptide per well.
Optimal dilutions to be determined by the researcher.
