Luteinizing Hormone (LH)
| Catalog Numbers: | LH Standard Grade – 160S LH High Purity – 160A |
Product Specification:
Luteinizing hormone is a gonadotropin and a glycoprotein having two subunits. The alpha subunit is similar to those of FSH, HCG, and TSH. The beta subunit is different from the other hormones and confers its biochemical specificity. LH is secreted by the basophilic cells of the anterior pituitary. LH is involved in the maturation of the ovarian follicles, ovulation and the formation of the corpus luteum. LH is available as whole molecule standard (50%) and High purity (95%) grades, or as alpha and beta subunits.
