Anti-insulin like 6 antibodies are used for the immunodetection of the protein encoded by the INSL6 gene. In humans, the canonical protein has a reported length of 213 amino acid residues and a mass of 24.9 kDa. It is known to be a secreted protein. It is reported to have testis-specific expression. A member of the Insulin protein family, it is suspected to have a role in sperm development and fertilization. Other names for this target antigen include insulin-like peptide INSL6, insulin-like peptide 5, insulin-like peptide 6, relaxin/insulin-like factor 1, and RIF1. Gene orthologs have been identified in the mouse, rat and chimpanzee species. Western Blot is the most common application for the insulin like 6 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
