일반 설명

FSH (follicle stimulating hormone) protein is composed of two subunits- α and β, where α subunit has resemblance to LH (luteinizing hormone), hCG (human chorionic gonadotropin) and TSH (thyrotropin-releasing hormone), which are glycoprotein hormones. α subunit has one glycosylation site and β subunit has two.

애플리케이션

Follicle stimulating hormone from sheep pituitary has been used for-
  • the in vitro maturation of bovine ovaries
  • the hormonal treatment of Sertoli cells
  • the intraperitoneal hormone treatment of male lizards
  • the intramuscular hormone treatment of American alligator (Alligator mississippiensis)
  • use in medium used for the maturation of bovine cumulus-oocyte complexes (COCs)

생화학적/생리학적 작용

FSH (follicle stimulating hormone) in involved in the growth of ovarian follicles and steroidogenesis of ovaries. FSHR (follicle stimulating hormone receptor) interacts with FSH in the ovaries, and determines the responsiveness to this hormone. Depressed levels of FSHR result in poor responsiveness and influence folliculogenesis. In Caucasian population, certain polymorphisms in FSHR gene are more commonly found in patients with polycystic ovary syndrome (PCOS).
The α-chain is not active; biological specificity is attributed to the β-chain. Induces maturation of Graafian follicles of the ovary; promotes development of germinal cells in males; activates cytosolic tyrosine kinase.

  5. Do you have information on the solution stability of Follicle Stimulating Hormone (FSH) from pituitary?

    For information on the solution stability of FSH (and much more), refer to Chem. Soc. Rev., 2(4), 355-395 (1973).From page 369:  "The stabilities of the most highly purified preparations of certain hormonal glycoproteins have presented some problems, e.g. follicle-stimulating hormone preparations are often found to be stable in frozen solution but lose activity dramatically on concentration and freeze drying." Based on that information, we would recommend that if you need to freeze solutions of FSH, you should flash-freeze the solution (using either liquid nitrogen or a dry ice-alcohol bath), and store the solution in the ultra-cold (-70 or -80°C) freezer. Since FSH does have some solution stability concerns, simply placing the solution in a -20°C freezer without first flash-freezing may reduce the activity.
