The 2 reddish collections we commonly use would be the antigen recognition products which can be judged being optimistic,antigen self test kit, which are derived from the principle of twice-antibody sandwich ELISA.
The trial was dropped around the trial pad, then passed on throughout the binding pad, diagnosis line (T collection) and high quality handle series (C range) on the response cushion in series by liquid chromatography. The binding pad contains colloidal golden or latex spheres labeled with antibodies that relocate with the sample.
If the sample contains malware, the virus binds for the antibody on the outside from the chromogenic component in the binding pad, and the T series transforms red-colored. The excess chromogenic sphere continues to go forward with the T collection. In the event it reaches the standard control collection (C line), it is going to bind to the coated antibody and correct the color part, so the C line will turn red.
Even so, when the test does not consist of infection, antigen-antibody certain binding does not take place because the example moves from the binding cushion until it actually gets to the C line and binds for the secondary antibody there, resulting in shade improvement, which shows that this chromatography procedure is smooth. At this time merely the C collection transforms reddish and it is adverse.
