The AllergenControl™ Crustacean Residue Lateral Flow Test features polyclonal antibodies directed against shrimp tropomyosin configured in both sandwich and competitive 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) and Competitive Test Line (0) results. In addition, the reagent zone includes a Procedural Control Line (C) to minimize the potential for false negative outcomes.
