Control Peptide for A0577 (antiserum) and A0577-05 (affinity purified antibody).
Catalog #A0577-10
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.
Sequence InformationSynthetic peptide 19aa sequence of human ASIC4. No significant sequence homology is detected with other ASIC-beta or other ASICs.
Location: ~N-terminal, Extracellular. Species Sequence Homology: Rat, mouse: 100%.
ApplicationsSuitable for use in ELISA and Antibody Blocking. Not suitable for use in Western Blot. Other applications not tested.
Recommended DilutionELISA: Coat ELISA plates at 1ug/ml; Dilute antibody as instructed.
Antibody Blocking: 5-10ug per 1ul A0577 (antiserum) or 1ug A0577-05 (affinity purified antibody).
Optimal dilutions to be determined by the researcher.
