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
