Principle
Ochrasensor is a competitive test involving specific antibodies with high affinity for OCHRA molecules.
The test requires the use of two components :
-
The first component is a microwell containing predetermined amount of antibody linked to gold particles.
-
The second is a dipstick made up of a set of membranes with specific capture lines.
For a valid test, the upper red control line has to be visible after the test.
When the reagent from the microwell is re-suspended with the cereal extract, specific antibodies will bind the analytes if present.
When the dipstick is dipped into the sample, the liquid starts running vertically on the dipstick and passes through capture zones.
When the sample is free of OCHRA, a colour development occurs at the “test” line, indicating the absence of OCHRA in the cereal sample.
On the opposite, the presence of OCHRA in the sample will not cause the appearance of the coloured signal at the “test” capture line
