Art. No.: R4303

Intended use

RIDA®QUICK CIS is an immunochromatographic test for the detection cow’s milk in milk or cheese of other species (sheep and goat).

General Information

Sheep’s milk and goat’s milk are much more expensive than cow’s milk, which is often used to extend sheep and goat’s milk. This means an adulteration of the product according to EU-law. RIDA®QUICK CIS test is capable to detect adulterations or mixtures up to 0.5 %. A positive result indicates that the sample has a cow milk content of 0.5 % or more.

The basis of the assay is the antigen-antibody reaction. The presence of cow’s milk in a sample is determined by the immunological detection of bovine IgG (an antibody class), which is a natural constituent of cow’s milk. In ultra high heated products the antibodies will be denatured. Therefore an adulteration with cow’s milk cannot be detected with the RIDA®QUICK CIS test in these kind of products.
