Relaxin ELISA kits are assays designed to detect the peptide hormone relaxin. A member of the insulin-like-growth factor family (IGF), it is produced by many reproductive tissues including corpus luteum, uterus, testis and prostate. Members of the relaxin family include relaxin 1, 2, 3, and insulin-like (INSL) peptides. It facilitates angiogenesis, parturition, uterine contraction and enhances the motility of spermatozoa. It also mediates hemodynamic changes during pregnancy. Visit the supplier page for more information about detection target, range and reactivity.
