The 3M™ Allergen Protein Rapid Kits are intended for screening for the presence of specific proteins in clean-in-place (CIP) final rinse water, environmental swab samples, food ingredients and processed food products.

The 3M Allergen Protein Rapid Kits utilize a lateral flow device (LFD) that is an immunochromatographic test method utilizing antibodies which are specific for the detection of proteins from specific allergenic foods. Positive results are visualized by the presence of three lines: a control line, a hook line and a test line, when the target protein is present in a defined range of concentration. These limits will vary by a specific protein assay, and the limit of detection may vary depending on the matrix tested. Samples containing high amounts of target protein in a sample may result in an invalid test which will result in the absence of the hook line and/or test line.
