Principle

The kit is a competitive test involving one antibody in a single operation. The test requires using of two elements. The first element is one microwell that containing antibody linked to colloidal gold. The second element is one test strip made up by a set of membranes with capture line. The “control” line printed in red is visible all the time and the other one is the specific “test” line. The unique line for Heavy metal Cadmium(Cd) is located below the “control” line. When the reagent in the microwell is re-suspended with sample, antibody could bind the corresponding analysts during the first 3-minutes incubation at 20-25℃. Afterwards, when the test strip is dipped into the microwell, the liquid starts running vertically on the test strip and passes through the capture zone. When the sample is free of Heavy metal Cadmium(Cd), a colour development occurs at the specific capture line, indicating the absence of the concerned analysts in the water,bean,corn,rice sample. On the contrary, the presence of Heavy metal Cadmium(Cd) in the sample will not cause the colored signal to appear at the specific capture line.
