Test Kits for the Accurate Detection of Melamine

Melamine, a by-product of the coal industry, is a chemical compound frequently used for the production of plastics, kitchenware, commercial filters, laminates or coatings.

Melamine is very high in nitrogen. This has led to its illegal addition to food and feed for alteration as the high nitrogen content increases the apparent amount of protein in standard measurement procedures.

Consequences of illegal melamine food adulteration

Melamine first became a topic of great discussion in 2007, when veterinary scientists determined it to be the cause of hundreds of pet deaths from pet food contamination.

In September 2008, melamine was found in milk and infant formula, where it had been added to give appearance of higher protein content. The presence of melamine led to kidney stones and renal failure among young children in China. More than 50,000 people became ill, with 4 infant deaths and more than 12,800 hospitalizations.

Fast and highly sensitive melamine analysis

The Romer Labs test kit portfolio covers 2 highly sensitive ELISA methods for the quantitative analysis of melamine in different food and feed matrices.




AgraQuant® test kits are accurate and reliable enzyme-linked immunosorbent assays (ELISA) in a quantitative format.

The AgraQuant® Melamine test kit has been validated for analyzing dried distillers grains, soy bean meal and pet food. The quantitation range is 10 - 250 ppm for wheat gluten samples and 2 - 50 ppm for other commodity matrices.

The AgraQuant® Melamine Sensitive test kit is an extremely sensitive ELISA method which has been specifically developed for the detection of melamine in egg and dairy products as well as other foods. The quantitation range is 0.1 - 5 ppm for milk, yogurt, yogurt drinks and eggs, and 0.5 - 25 ppm for milk powder and biscuit samples.

Both the AgraQuant® Melamine and AgraQuant® Melamine Sensitive test kits come complete with melamine standards, antibody coated microwells, a sample diluent, a wash buffer, an enzyme conjugate, a substrate and a stop solution.
