Anti-HCRCN81 antibodies enable researchers to detect and measure the HCRCN81 antigen in biological samples. This target is a reported synonym of the C2orf68 gene, which encodes chromosome 2 open reading frame 68. The human version of HCRCN81 has a canonical amino acid length of 166 residues and a protein mass of 18.8 kilodaltons, although 2 isoforms have been identified. HCRCN81 is a member of the UPF0561 protein family.
