These hHa1 ELISA kits are immunodetection tools for measuring the levels of hHa1 in biological samples. hHa1 is an alias of the human KRT31 gene, which encodes the protein, keratin 31. Notably, hHa1 is known to play a role in epidermis development and epithelial cell differentiation, among other functions. The KRT31 protein is described to be 416 amino acid residues in length and 47.2 kilodaltons in mass. Other names for this target antigen include HA1, Ha-1, and KRTHA1.
