Equine Chorionic Gonadotropin

Endocrine Reviews, 1991
Cells from the chorionic girdle of the equine trophoblast invade the maternal endometrium at day 36 of gestation and become established as secretory elements known as the endometrial cups. These structures, which persist for 40-60 days, produce a gonadotropin which can be found in circulation until about day 130 of gestation. This glycoprotein has been

Enhancing Fertility in Mares: Recombinant Equine Gonadotropins

Journal of Equine Veterinary Science, 2019
Advanced reproductive technologies have been developed to enhance fertility in mares and stallions. Some of these technologies in mares include superovulation, embryo transfer (ET), intracytoplasmic sperm injection (ICSI), oocyte transfer (OT), gamete intrafallopian transfer (GIFT), and cloning.

Reduction and reoxidation of equine gonadotropin alpha-subunits.

Endocrinology, 1992
Ovine (o) and equine (e) LH alpha-subunits were reduced and reoxidized using conditions known to be effective for bovine and human alpha-subunits. The major product of oLH alpha refolding was alpha-subunit monomer. In contrast, eLH alpha formed a 121,000 mol wt aggregate. Monomeric eLH alpha was recovered, but in greatly reduced yield.

Structural studies on equine chorionic gonadotropin

Journal of Protein Chemistry, 1982
The amino acid sequence of the α subunit of equine chorionic gonadotropin (eCG, also pregnant mare serum gonadotropin, PMSG) has been determined. Overlapping peptides from tryptic and chymotrypic digests were isolated by a two-dimensional peptide mapping technique and sequenced by the Edman procedure. The proposed amino acid sequence of eCG α is:

Variations in the properties of equine chorionic gonadotropin

Theriogenology, 1981
The objectives of this paper are to review the chemical and biological properties of equine chorionic gonadotropin (eCG, PMSG) isolated from the serum. Comparisons are made with eCG isolated from endometrial cups, trophoblast cell culture medium, and low titer serum.

The Preparation and Properties of Equine Pituitary Gonadotropin

Journal of the American Pharmaceutical Association (Scientific ed.), 1950
A method is described for the alkaline extraction of equine pituitary glands which produced gonadotropic hormone, containing only traces of foreign protein but which was contaminated with posterior pituitary extract. Equine pituitary gonadotropin was found to possess a lower potency than that of serum gonadotropin.

STUDIES ON THE STABILITY OF EQUINE GONADOTROPIN IN CRUDE AND IN PURIFIED FORM

The Journal of Clinical Endocrinology & Metabolism, 1950
IN STUDYING the biologic and chemical properties of equine gonadotropin, a factor of immediate concern is the stability of the hormone under varying conditions. Furthermore, for clinical purposes, it is desirable that the hormone be highly purified.
