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).
