Anti-KCNJ10 antibodies are used in the immunodetection of the protein potassium inwardly rectifying channel subfamily J member 10. In humans, the canonical protein has a reported length of 379 amino acid residues and a mass of 42.5 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the kidney. A member of the Inward rectifier-type potassium channel (TC 1.A.2.1) protein family, KCNJ10 is believed to be responsible for potassium buffering action of glial cells in the brain. KCNJ10 is also used as a cellular marker for characterizing astrocytes. Synonyms for this target antigen include KCNJ13-PEN, KIR1.2, KIR4.1, SESAME, and BIRK-10. KCNJ10 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Over 210 citations in the literature describe the use of KCNJ10 antibodies in research. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunohistochemistry are also common applications.
