Anti-KCNK18 antibodies are used in the immunodetection of the protein potassium two pore domain channel subfamily K member 18. In humans, the canonical protein has a reported length of 384 amino acid residues and a mass of 43.7 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in dorsal root ganglion and trigeminal ganglion neurons. A member of the Two pore domain potassium channel (TC 1.A.1.8) protein family, KCNK18 is known to be involved with potassium ion transport and the transport of ions. The KCNK18 gene has been associated with the disease, Migraine with or without aura. Synonyms for this target antigen include TWIK-related individual K+ channel, TWIK-related individual potassium channel, TWIK-related spinal cord K+ channel, TWIK-related spinal cord potassium channel, and potassium channel subfamily K member 18. A number of KCNK18 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
