Anti-SELK antibodies enable researchers to detect and measure the SELK antigen in biological samples. This target is a reported synonym of the SELENOK gene, which encodes selenoprotein K. This protein is known to function in the transport of ions and cellular localization, among other biological roles. The human version of SELK has a canonical amino acid length of 94 residues and a protein mass of 10.6 kilodaltons. It is reported to be localized in the ER and cell membrane of cells. SELK is a member of the Selenoprotein K protein family. Indicated applications for SELK antibodies listed below include ELISA, Western Blot, and Immunofluorescence.
