Anti-KRTHB5 antibodies enable researchers to detect and measure the KRTHB5 antigen in biological samples. This target is a reported synonym of the KRT85 gene, which encodes keratin 85. This protein is known to function in epidermis development, among other biological roles. The human version of KRTHB5 has a canonical amino acid length of 507 residues and a protein mass of 55.8 kilodaltons. It is reported to be notably expressed in the hair. KRTHB5 is a member of the Intermediate filament protein family.
