Anti-HTX5 antibodies enable researchers to detect and measure the HTX5 antigen in biological samples. This target is a reported synonym of the NODAL gene, which encodes nodal growth differentiation factor. This protein is known to function in brain development and cell proliferation, among other biological roles. The human version of HTX5 has a canonical amino acid length of 347 residues and a protein mass of 39.6 kilodaltons. It is reported to be a secreted protein. This target antigen may also be known as nodal homolog.
