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.

EuroProxima Plus Cow´s Milk

Art. No.: 5171MILK

Intended use:

A competitive enzyme immunoassay for the detection of raw and heat-treated cow’s milk in milk from other species.

General Information:

The Plus Cow’s Milk ELISA is a fast screening tool for the detection of cow’s milk residues in milk products from other species. The test can be used for such purposes as:

  • Quality control of the incoming goods, for example for the detection of residues of cow’s liquid milk in goat’s liquid milk batch to detect contamination before a batch is processed further.
  • Quality control of a final product, for example for the detection of residues of cow’s milk powder in goat’s milk powder as a result of cross-contamination between production batches.


  • Validated with different samples from dairy companies, both liquid and powder samples.
  • Applicable for fresh and heat-treated samples.
  • Short assay time (45 minutes in total).
