Anti-KRTAP13-1 antibodies are used in the immunodetection of the protein keratin associated protein 13-1. In humans, the canonical protein has a reported length of 172 amino acid residues and a mass of 18.3 kDa. It is a member of the PMG protein family. Synonyms for this target antigen include high sulfur keratin associated protein 13.1. KRTAP13-1 gene orthologs have been reported in the mouse species. These KRTAP13-1 antibodies are widely used in ELISA experiments, among other applications.
