Anti-ARL13 antibodies enable researchers to detect and measure the ARL13 antigen in biological samples. This target is a reported synonym of the ARL13A gene, which encodes ADP ribosylation factor like GTPase 13A. The human version of ARL13 has a canonical amino acid length of 290 residues and a protein mass of 33 kilodaltons, although 2 isoforms have been identified. ARL13 is a member of the Arf protein family.
