Native protein


Native Porcine Luteinizing Hormone is a glycosylated, polypeptide chain which stimulates maturation of follicle, induces ovulation, accelerates formation of corpus luteum and secretion of pregnanolone. Porcine Luteinizing Hormone delays ovulation and ovarian cyst.




Sterile filtered and lyophilized with no additives.


It is recommended to reconstitute the lyophilized Porcine LH in sterile 18M-cm H2O at 100IU/4ml, which can then be further diluted to other aqueous solutions.




Lyophilized Porcine LH is stable at room temperature for 3 weeks. Upon reconstitution LH should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.


Research topic



Luteinizing hormone is a part of a neurological pathway comprised of the hypothalamus, the pituitary gland, and gonads. In this pathway, LH release is stimulated by gonadotropin-releasing hormone (GnRH) and inhibited by estrogen in females and testosterone in males. LH has various functions, which differ between male and female. In both sexes, LH contributes to the maturation of primordial germ cells. In male, LH causes the Leydig cells of the testes to produce testosterone. In female, LH triggers the creation of steroid hormones from the ovaries. Additionally, LH in female, plays roles in both ovulation and implantation of an egg in the uterus.
