Anti-KCNJ2 antibodies are used in the immunodetection of the protein potassium inwardly rectifying channel subfamily J member 2. In humans, the canonical protein has a reported length of 427 amino acid residues and a mass of 48.3 kDa. Its subcellular localization is in the membrane. It is notably widely expressed in many tissue types. A member of the Inward rectifier-type potassium channel (TC 1.A.2.1) protein family, KCNJ2 is suspected to be participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Synonyms for this target antigen include HHBIRK1, HHIRK1, IRK1, KIR2.1, LQT7, SQT3, inward rectifier potassium channel 2, and ATFB9. KCNJ2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of KCNJ2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
