Anti-TSPAN23 antibodies are used in antigen-specific immunodetection in biological samples. The target TSPAN23 is a known alias name of the protein retinal outer segment membrane protein 1, encoded by the ROM1 gene in humans. This 351-amino acid residue protein is reported to play a role in rod outer segment (ROS) morphogenesis (By similarity). It is reported to be expressed in the retina.
