基层民警办案时对吸食违禁品行为进行检测判定
 

[principles of inspection]

Morphine (Morphine) is an opioid alkaloid extracted from opium. It is a pure opioid receptor agonist and has powerful analgesic effect. Therefore, morphine is an analgesic drug in medicine. This kind of substance has the euphoria at first, can not concentrate, can produce the illusion phenomenon, the excessive use causes the acute poisoning, extremely easy to bear the tolerance and the addiction. Morphine mainly excreted in urine by the kidneys, and morphine accounted for 2-12%, most of which (60-80%) were morphine gluconate. Opioid toxins (including opiates, heroin, morphine, codeine) enter the body and are metabolized mainly through the liver and are rapidly de acylated into 6-, which is further reduced to morphine. Therefore, the presence of morphine or its metabolites in urine and exceeding the threshold indicate that opioid banned substances have been used.
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 without red ribbon showed positive results. If no concentration of morphine or morphine in urine concentration is below the threshold, the antibody colloidal gold of morphine combined with morphine or not is not saturated, so the colloidal gold on morphine combined with antibody and the detection regions on the membrane of morphine, the detection zone to capture the colloidal gold particles appear red ribbon, negative results.
