| Assay principle |
This kit uses the principle of Colloidal Gold Immunochromatography assay. It can detect Phenethylamine A (PHEA) in urine sample. After adding the sample solution into the sample well of detection card, PHEA of the sample solution combine with the gold-labelled antibody, so as to prevent the combining of gold-labelled antibody with PHEA conjugate on the cellulose membrane. When the concentration of PHEA in the sample solution is more than the detection limit, the detect line do not show color and the result is positive. When the concentration of PHEA in the sample solution is less than the detection limit, the detect line show color and the result is negative. |
