Anti-Retbindin antibodies are used for the immunodetection of the protein encoded by the RTBDN gene. In humans, the canonical protein has a reported length of 229 amino acid residues and a mass of 24.6 kDa. Its subcellular localization is in the extracellular matrix, cell membrane, and is secreted. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in peripheral retina. A member of the Folate receptor protein family, it is reported to be a riboflavin-binding protein, which might have a role in retinal flavin transport. Post-translational modifications have been described, including N-glycosylation. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species. Western Blot is a widely used application for the Retbindin antibodies listed below. In addition, ELISA is also a common application.
