Description

Gonadotropin-Releasing Hormone (GnRH) Human, also known as Luteinizing-hormone releasing hormone (LHRH), recombinantly produced in E. coli cells, is a non-glycosylated polypeptide chain containing 92 amino acids (24-92 a.a.) and has a molecular mass of 10.3kDa.

GnRH is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Summary

GnRH is a peptide hormone responsible for the release of FSH and LH from the anterior pituitary. GnRH is synthesized and released by the hypothalamus. 

At the pituitary, GnRH stimulates the synthesis and secretion of the follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These processes are controlled by the size and frequency of GnRH pulses, as well as by feedback from androgens and estrogens. Low frequency GnRH pulses lead to FSH release, whereas high frequency GnRH pulses stimulate LH release.
There are differences in GnRH secretion between males and females. In males, GnRH is secreted in pulses at a constant frequency, but in females the frequency of the pulses varies during the menstrual cycle and there is a large surge of GnRH just before ovulation.


GnRH secretion is pulsatile in all vertebrates, and is necessary for correct reproductive function. Thus, a single hormone, GnRH, controls a complex process of follicular growth, ovulation, and corpus luteum maintenance in the female, and spermatogenesis in the male.
