FFHP Membranes

A thinner, backed membrane with reduced surfactant content and highly consistent performance for use with most sample types in a lateral flow assay and available in three grades - FF80HP, FF120HP and FF170HP.

- FF80HP Plus - For use with high density samples (e.g., undiluted serum).
- FF120HP Plus - For use with viscous samples and to reduce reagent dispensing rates to save cost.
- FF170HP - For use with low viscosity samples.
- Exceptional intra- and inter-lot consistency as demonstrated by a coefficient of variation (CV) for capillary rise of < 10%.
- Complete documentation: Validation guides, certificates of quality, and extractables data are available for all manufacturing flow kits

FFHP Membranes
FF High Performance (HP) membranes are part of the AE family, which are directly cast onto a plastic film. The FFHP membranes are a result of improved membrane casting procedures, which result in enhanced intra- and inter lot consistency and sharper lines. The surface is uniform without unincorporated nitrocellulose powder and the fine structure fiber distribution provides large internal surfaces for binding proteins. FFHP membranes provide reduced assay optimization costs, compared to a less consistent membrane and reproducible limits of detection.

Nitrocellulose Membranes
Nitrocellulose membranes are a key functional part of lateral-flow assays. The membrane must provide sufficient protein binding to enable the formation of a sharp and intense capture line, but at the same time the level of nonspecific background must be low for easy interpretation of results. Nitrocellulose membranes are available in a range of wicking rates and formulations. It has long been known that the wicking rate of a membrane has a significant impact on test sensitivity.
