Technical Guide: How to Choose the Right Nitrocellulose Membrane Speed for LFA
Understanding Capillary Flow Time (Sec/4cm) One of the most critical parameters in Lateral Flow Assay (LFA) development is the wicking speed of the nitrocellulose membrane. Often measured as the time required for liquid to travel 4cm (e.g., HF135, HF180), choosing the wrong speed can ruin assay sensitivity. Fast vs. Slow Membranes: The Trade-off Membrane Type … Read more
