Human anti-ASIC1 (Acid-sensing ion channel 1) antibody ELISA kit

ELISA Type: Indirect ELISA. Detection Range: 3.125-200µg/mL. Sensitivity: 1.875µg/mL. Sample Types: Serum, Plasma, Cell Culture Supernatant, cell or tissue lysate, Other liquid samples. Protein function: Isoform 2 and isoform 3 function as proton-gated sodium channels, they are activated by a drop of the extracellular pH and then become rapidly desensitized. The channel generates a biphasic current with a fast inactivating and a slow sustained phase. Has high selectivity for sodium ions and can also transport lithium ions with high efficiency. Isoform 2 can also transport potassium, but with lower efficiency. It is nearly impermeable to the larger rubidium and cesium ions. Isoform 3 can also transport calcium ions. Mediates glutamate- independent Ca(2+) entry into neurons upon acidosis. This Ca(2+) overloading is toxic for cortical neurons and may be in part responsible for ischemic brain injury. Heteromeric channel assembly seems to modulate channel properties. Functions as a postsynaptic proton receptor that influences intracellular Ca(2+) concentration and calmodulin-dependent protein kinase II phosphorylation and thereby the density of dendritic spines. Modulates activity in the circuits underlying innate fear. [The UniProt Consortium]
