檢測違禁品濫用食品、藥品添加試劑板

The antibody - antigen - specific binding reaction and immune membrane chromatography technique were used to detect morphine in human urine by immune competitive inhibition method. That is, protein labeled morphine (morphine carrier), which competes with morphine in urine, competes for antigen binding sites on limited antibodies.
A detection cup cover strip, the strip test area (T) coated -BSA morphine carrier conjugates, the other end is fixed with morphine monoclonal antibody colloidal gold disk. If the urine containing morphine, morphine in urine and immobilized on nitrocellulose membrane labeled colloidal gold in morphine competition on morphine antibody antigen binding sites, when the above threshold concentration of morphine concentration in urine to product design, they will be the first with morphine monoclonal antibody and colloidal gold paper occupy all the binding sites of morphine antigen antibody, thus preventing the colloidal gold detection zone on morphine antibody and on the membrane of morphine combined detection area can not capture the colloidal gold particles instead of red ribbon, Yang
