Product Description
OchraSensor Quanti is a rapid assay in dipstick format detecting quantitatively the contamination of cereals samples by Ochraoxins molecules
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.
Good to know
Ochratoxins are a group of mycotoxins produced by some Aspergillus species and some Penicillium species.
Ochratoxin A is known to occur in commodities such as cereals, coffee, dried fruit, and red wine. It is possibly a human carcinogen and is of special interest as it can be accumulated in the meat of animals. Thus, meat and meat products can be contaminated with this toxin. Exposure to ochratoxins through diet can cause acute toxicity in mammalian kidneys.
