Equine chorionic gonadotropin (acronym given as eCG but not to be confused with ECG) is a gonadotropic hormone produced in the chorion of pregnant mares. Previously referred to as pregnant mare's serum gonadotropin (PMSG), the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination.

孕马血清促性腺激素，即PMSG（Pregnant Mare Serum Gonadotropin） 。也称为马绒毛膜促性腺激素。它是在怀孕母马血清中发现的一种激素。并已知在妊娠马属动物(驴、斑马等)都有产生，所以有人称为马属动物绒毛膜促性腺激素(eCG)。

孕马血清促性腺激素（PMSG）：它是英国科学家Cole和Hart在怀孕母马血清中发现的一种重要的激素，是由马属动物胎盘的尿囊绒毛膜细胞分泌的，具有促进卵泡发育、排卵和黄体…

Until recently, the only eCG products available in the market for veterinary use consisted in partially purified preparations of pregnant mare serum gonadotropin (PMSG). Here, a bioactive recombinant eCG (reCG) produced in suspension CHO-K1 cells was purified employing different chromatographic methods (hydrophobic interaction chromatography ...

In the pig, equine chorionic gonadotropin (eCG), also called pregnant mare's serum gonadotropin (PMSG), is the most commonly used and most effective product for induction of follicular growth, estrus, and ovulation in swine. In many European countries, eCG is commercially available for inducing estrus in sows and gilts.

Pregnant mare serum gonadotropin (PMSG), also known as equine chorionic gonadotropin (eCG), is a hormone that is secreted by the endometrial cups formed in the mare uterus ~40 days after conception. Concentration of PMSG is measurable in most mares by day 45, rises rapidly and peaks at about 60 days, and is no longer detectable 100 - 150 days ...

2025年2月25日 · The commercially available eCG products are crudely purified from the serum of pregnant mares, hence called pregnant mare serum gonadotropin (PMSG). Appropriate glycosylation of the protein is...

Equine chorionic gonadotrophin (eCG – formerly known as pregnant mare serum gonadotrophin (PMSG)) is present in high concentrations in serum between days 40 and 120. False positives can be recorded if the fetus dies, because the endometrial cups …

2023年1月18日 · eCG is secreted by trophoblastic cells to the blood of pregnant mares during the 2nd to 5th months of pregnancy, with a peak level at 70–80 days of pregnancy. For this reason, eCG is known as PMSG. However, considerable variations between mares, in both the timing of the peak and the eCG amount found in serum, have been reported.

PMSG is a placental glycoprotein hormone prepared from the serum of pregnant mares. PMSG consists of alpha subunit and beta subunit. It has both Follicle Stimulating Hormone like activities and Luteinizing Hormone (LH) like activities. Jiagen Biotechnologies supplies quality PMSG of various specifications.
