HCG Powder

Human chorionic gonadotropin  is a hormone for the maternal recognition of pregnancy produced by trophoblast cells 

Human chorionic gonadotropin (HCG) is a glycoprotein secreted by trophoblast cells of the placenta And β dimer proteins. The molecular weight of glycoprotein hormone 36700, A. Pituitary, FSH, follicle stimulating hormone, LH (luteinizing hormone) and TSH (thyroid stimulating hormone) are basically similar, So they can cross-react with each other, while the structure of β subunit is not similar. In mature women, the fertilized ova move to the uterine cavity for implantation and form embryos. In the process of development and growth into the fetus, the placental syncytiotrophoblast cells produce a large amount of HCG, which can be excreted into urine through the blood circulation of pregnant women. Serum and urine HCG levels rise Rapidly from 1 to 2.5 weeks of gestation, reaching a peak at 8 weeks of gestation and dropping to moderate levels at 4 months of gestation, which remain at the end of gestation. At present, the commonly used detection methods are: latex aggregation inhibition test and hemagglutination inhibition test; Radioimmunoassay (RIA); Enzyme linked immunosorbent assay (ELISA); Monoclonal antibody colloidal gold test
