Description: Tissue acidosis that occurs in ischemia, tissue damage or inflammation is accompanied by pain. Proton-gated cation channels are activated by low pH in nociceptive neurons. H+-gated channels are members of the NaC/DEG superfamily that include: (1) Amiloride-sensitive epithelial Na+ channels (a, b, and g, and d-ENaC subunits); (2) A FMRFamide-gated channel (FaNaC); (3) mechanosensory channel proteins of nematode degenerins (DEG). NaC/DEG superfamily is characterized by intracellular N- and C-termini, two transmembrane domains, and a large extracellular loop. All members of this family are selective for Na+ and blocked by amiloride. The mammalian homolog of degenerins (MDEG or MDEG1; now designated ASICs for Acid Sensing Ion Channels). Three are at least 4 distinct proteins in ASIC family ASIC1-4. AISC4/SPASIC (human 539/666aa, chromosome 2; rat 539aa, ~97% homology between rat and human) is strongly expressed in pituitary and also detected in most areas of brain. ASIC4 is the most divergent member of ASIC family showing only 45% identity with ASIC1-3. ASIC4 is not activated by low pH. It may associate with other ASICs to form a functional channel. Applications: Suitable for use in Western Blot and ELISA. Other applications not tested. Recommended Dilution: Western Blot: 1-10ug/ml (ECL) ELISA: 0.5-1ug/ml. Coat ELISA plates at 1ug/ml with Control Peptide. Optimal dilutions to be determined by the researcher. Control Peptide: A0577-10: Acid Sensing Ion Channels 4, Human (ASIC4) 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. |
