The Hook Test Advantage

The hook effect or prozone effect is well-recognised immunologic phenomenon where the effectiveness of antibody based assays can impaired when there are high concentration of the target allergen. This can produce false negative results for highly contaminated samples that pose a high risk to allergy sufferers. The 3M Allergen kits have an additional Hook Line detection system in their strips to identify this problem, providing great confidence and security in your allergen reporting.  

Reading LFD

Each test kit comes complete with strips, extraction tubes, an extraction buffer and quick guide.

Milk Allergens

Milk represents one of the largest food allergens, especially for children and is therefore important that products are labelled correctly. The risk of hidden proteins in food such as sausages, cookies and ready-to-eat meals represent a critical problem for allergic people. Approximately 80% of bovine milk proteins are composed of α, β, and κ-Caseins. These proteins are a major component of cheese, and due to their resistance to heat can be found in many other dairy products, thus representing a ubiquitous allergen. The 3M™ Milk Protein Rapid test kit offers food manufacturers a tool to prevent the release of product contaminated with this allergen.
