Anti-INSL3 Antibody

Produced in rabbit as a polyclonal reagent and supplied at 100 µl per vial, this unconjugated primary antibody targets the insulin-like peptide 3 hormone (also known as Relaxin-like factor) for Western blot and immunohistochemistry on human samples. INSL3 is secreted by testicular Leydig cells in males and theca interna cells in females, where it signals through the RXFP2/GREAT receptor to drive gubernaculum-mediated testicular descent in the fetus and to maintain adult Leydig cell function, ovarian follicle biology, and bone metabolism. Available from Antibodies.com, this reagent is validated for research use in studies of cryptorchidism, androgen biosynthesis, and reproductive endocrinology, where circulating INSL3 is widely used as a serum biomarker of functional Leydig cell mass. Because the antibody is polyclonal, multiple epitopes along the processed A and B chain regions of the mature peptide are typically recognized, and the unconjugated format leaves the choice of HRP, biotin, or fluorophore labeling open to the end user. The product ships as a single-use vial sized for routine western blotting and IHC staining protocols.
