The MaxSignal® No-Mel Milk Total Protein Assay Kit is a colorimetric assay for the determination of protein in milk, powdered milk, cream, ice cream and chocolate drink.

MaxSignal® No-Mel Milk Total Protein Assay Kit uses a dye-binding assay to determine protein in milk and other dairy products. The kit enables international and government regulatory agencies, food manufacturers and processors, as well as quality assurance organizations, to determine protein levels in dairy products in response to customer concerns about food safety. The test is based on a proven AOAC-approved method for milk protein determination. The MaxSignal® No-Mel Milk Total Protein Assay Kit contains sufficient materials to test 42 dairy samples.

The assay detects the specific binding of milk proteins to dye molecules. This detection is fundamentally different than that of some other protein determination methods (such as the Kjeldahl method) which detect protein via nitrogen and are vulnerable to contamination of amine containing impurities such as melamine. The MaxSignal® No-Mel Milk Total Protein Assay Kit provides accurate, proven results even in the presence of high levels of melamine.

The kit contains all reagents, including standards and buffers, required to perform the test. Materials and chemicals necessary for extraction of clenbuterol from sample material are not included in the test-kit. Procedures for extraction of clenbuterol from the samples are described in detail in the manual.
