Porcine Luteinizing Hormone (LH) Native Protein is a glycosylated, polypeptide chain which stimulates maturation of follicle, induces ovulation, accelerates formation of corpus luteum and secretion of pregnanolone.
Luteinizing hormone (LH) is produced in both men and women from the anterior pituitary gland in response to luteinizing hormone-releasing hormone (LH-RH or Gn-RH), which is released by the hypothalamus. LH, also called interstitial cell-stimulating hormone (ICSH) in men, is a glycoprotein composed of two non covalently associated dissimilar amino acid chains, alpha and beta. The alpha chain is similar to that found in human thyroid-stimulating hormone (TSH), follicle stimulating hormone (FSH), and human chorionic gonadotropin (hCG). The difference between these hormones lie in the amino acid composition of their beta subunits, which account for their immunological differentiation. In both males and females, LH works upon endocrine cells in the gonads to produce androgens.
Sterile-filtered white lyophilized (freeze-dried) powder. The LH was lyophilized with no additives.
It is recommended to reconstitute the lyophilized Porcine LH in sterile 18M-cm H2O at 100 IU / 4 ml, which can then be further diluted to other aqueous solutions.
Ships ambient temperature. Upon receipt, store the product at the temperature recommended below.
Lyophilized Porcine LH, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. 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). Please prevent freeze-thaw cycles.
