Peanut Lateral Flow

The peanut is a ground nut belonging to the legume family. As with other nuts, peanuts constitute a relatively common cause of food allergy capable of triggering severe allergic reactions in sensitive individuals. Accordingly, numerous countries require that food labels clearly indicate peanut content. To assist the food industry in establishing effective food safety practices, AllergenControl™ has developed a rapid test kit that can reliably detect Peanut residues in food and on surfaces and equipment.

Intended Use

This test kit is designed for use in the qualitative determination of peanut residues obtained from sampling foods (solids, powders, and liquids) and environmental surfaces. The test is intended for laboratory use only and should only be performed by trained personnel.

Assay Principles

The AllergenControl™ Peanut Residue Lateral Flow Test features polyclonal antibodies directed against peanut proteins configured in a sandwich format. To operate the kit, the sample is first subjected to a short extraction step. The sample extract is then directly applied to the lateral flow device sample port, where it is allowed to migrate across the reagent zone thus enabling visualization of the Sandwich Test Line (T) results. In addition, the reagent zone includes a Procedural Control Line (C) to minimize the potential for false negative outcomes.
