Description_x000D_ General description_x000D_ Luteinizing hormone (LH) is secreted by the gonadotrophic cells, localized in the anterior pituitary gland. Human LH consists of an α and β subunit, which are encoded by the gene mapped to human chromosome 6q12–q21 and 19q13.32 respectively._x000D_ Immunogen_x000D_ Native purified human Luteinizing Hormone from human pituitary glands._x000D_ Mouse monoclonal antibody raised against a Luteinizing Hormone._x000D_ Physical form_x000D_ Solution in phosphate buffered saline, pH 7.4_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Luteinizing hormone (LH) along with human chorionic gonadotropin (hCG), plays an essential role in the reproductive cycle.
