Description: 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 300 aa 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, and is able to mediate anion exchange by itself. Human AE2 gene (chromosome 7q35-q36) encodes a protein of 124 aa (mouse 1237 aa, rat 1234aa). Several isoforms of AE2 are also expressed as a result of alternative splicing. AE2 is widely expressed in many tissues. Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:1000-1:5000 ELISA: 1:10,000-50,000 Optimal dilutions to be determined by the researcher. Control Peptide: A2295-14D1 Anion Exchanger 2, Rat Control Peptide Storage and Stability: May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
