Soy Milk Lateral Flow

Allergies to soy are relatively common and can present as life-threatening allergic reactions. Accordingly, numerous countries require that food labels clearly indicate soy content. Soy prepared as a “milk” substitute for dairy has been subjected to prolonged thermal processing rendering the allergens relatively indiscernible using standard detection methods. To address this issue, AllergenControl™ has developed a rapid test kit that can reliably detect Soy Milk residues in food and on surfaces and equipment.

Intended Use

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

Assay Principles

The AllergenControl™ Soy Milk Residue Lateral Flow Test features polyclonal antibodies directed against soy milk proteins 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.
