WebHuman Chorionic Gonadotropin (hCG), Beta Subunit, Quantitative Special Instructions Values obtained with different assay methods should not be used interchangeably in … WebBeta-hCG is a family of pituitary and placental glycoprotein hormones that share the same alpha subunit and differ in the beta subunit from follicle stimulating hormone, luteinizing hormone and thyroid stimulating hormone. Because the alpha subunit is common to several pituitary hormones, serum assays measure the beta subunit. [1]

Urinary concentrations of beta core fragment of hCG throughout pregnancy. Obstet … The β-subunit of hCG gonadotropin (beta-hCG) contains 145 amino acids, encoded by six highly homologous genes that are arranged in tandem and inverted pairs on chromosome 19q13.3 - CGB (1, 2, 3, 5, 7, 8). It is known that CGB7 has a sequence slightly different from that of the others. Visualizza altro Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually … Visualizza altro Human chorionic gonadotropin is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5kDa αhCG and 22.2kDa βhCG. Visualizza altro Naturally, it is produced in the human placenta by the syncytiotrophoblast. Like any other gonadotropins, it can be extracted … Visualizza altro Blood or urine tests measure hCG. These can be pregnancy tests. hCG-positive can indicate an implanted blastocyst and mammalian embryogenesis or can be detected for a … Visualizza altro Human chorionic gonadotropin interacts with the LHCG receptor of the ovary and promotes the maintenance of the corpus luteum for the maternal recognition of pregnancy at the beginning of pregnancy. This allows the corpus luteum to secrete the hormone Visualizza altro Three major forms of hCG are produced by humans, with each having distinct physiological roles. These include regular hCG, hyperglycosylated hCG, and the free beta-subunit of hCG. Degradation products of hCG have also been detected, including … Visualizza altro Tumor marker Human chorionic gonadotropin can be used as a tumor marker, as its β subunit is secreted by some cancers including seminoma, choriocarcinoma, germ cell tumors, hydatidiform mole, teratoma with elements of Visualizza altro WebIRP Chorionic Gonadotrophin Beta Subunit, Human, For Immunoassay NIBSC code: 75/551 Instructions for use (Version 4.0, Dated 28/03/2013) 1.
