How to Select the Best Surfactant for Your Lateral Flow Assay

Download this application note to learn about surfactant classes, their function in lateral flow assays, and how they can affect target detection

Lateral flow assays (LFA) are widely used for molecular detection, particularly in the point-of-care market. Assay performance is affected by the type and concentration of surfactant used, so it is recommended to screen a variety of surfactants and concentrations.

In this resource, you will learn about general classification of surfactants and their function in lateral flow assays. Furthermore, you will learn about the findings of a study on how surfactants can affect the following aspects of target detection:

  • Signal intensity 
  • Background clearance
  • Non-specific binding
  • Interaction of carrier proteins and antibodies
