Product Detials:Human chorionic gonadotropin (HCG) is a glycoprotein hormone secreted by trophoblastic cells of placenta. A molecule of HCG consists of two noncovalently bound subunits: Alpha- and beta-HCG. Beta-subunit is specific for HCG hormone. Determination of HCG is widely used for early diagnosis of pregnancy. Multiple pregnancy results in correspondent elevation of serum HCG; While ectopic pregnancy and placental insufficiency cause decreased serum HCG levels. Determination of HCG in serum during second trimester is used for pregnancy monitoring, especially in screening for Down syndrome, along with other laboratory tests (AFP and Estriol). Serum HCG is also a laboratory marker of trophoblastic tumours - chorionepitheliomas, some seminomas and theratomas. Serial determination of serum HCG can be used for therapy monitoring in these cancers. The present test system uses beta chain specific monoclonal antibody XK27 as the capture, and alpha-chain specific monoclonal antibody XK77 as the tracer; Therefore only the whole intact HCG molecule is detected. ASSAY PRINCIPLE This test is based on two-site sandwich enzyme immunoassay principle. Tested specimen is placed into the microwells coated by specific anti-HCG-antibodies. Antigen from the specimen is captured by the antibodies coated onto the microwell surface. Unbound material is removed by washing procedure. Second antibodies directed towards another epitope of HCG, and labelled with peroxidase enzyme, are then added into the microwells. After subsequent washing procedure, the remaining enzymatic activity bound to the microwell surface is detected and quantified by addition of chromogen-substrate mixture, stop solution and photometry at 450 nm. Optical density in the microwell is directly related to the quantity of the measured analyst in the specimen. Trademark: JD Model NO.: JE002 Company: Jei Daniel Biotech Corp.
