Overcoming Matrix Interference in Food Allergen Lateral Flow Assays
The Challenge of Complex Food Matrices Detecting allergens like peanut, soy, or gluten in processed foods is notoriously difficult. Unlike clean clinical samples (serum/buffer), food extracts are often viscous, high in fats, and loaded with proteins that cause non-specific binding. This leads to the “Matrix Interference” effect, often resulting in false positives or membrane clogging. … Read more
