FF High Performance Nitrocellulose Membranes Optimized for Diagnostic Assay Reproducibility

GE Healthcare Life Sciences’ new WhatmanTM FF High Performance (HP) membrane provides the industry with a new diagnostic membrane to enable fast, razor-sharp line separation and highly reproducible results for the detection of target molecules in liquids such as water, urine, blood and saliva. The target molecules may include drugs, hormones, proteins, antibodies, nucleic acids, whole bacteria and viruses.

GE Healthcare’s FF HP membrane is suitable for use in lateral flow assay manufacture as it provides improved reliability and rapid results. The new membrane is produced using an innovative casting method to yield a uniform, new powder-free surface that delivers a coefficient of variation in capillary rise of < 10 %. Both the intra- and inter- lot consistency of the new membrane was tested through analysis of over 1000 samples giving a low coefficient of variation. This excellent reproducibility improves the consistency of assays and offers a more reliable limit of detection, which in turn reduces the costs of assay optimization for researchers.

Three FF HP membranes are available with different capillary rise times (wicking rate); allowing researchers to choose the most suitable membrane for their assay.
