Membrane designed for diagnostic assay reproducibility
The FF HP membrane from GE Healthcare delivers a coefficient of variation in capillary rise of < 10 %.
The new Whatman FF High Performance (HP) membrane provides the industry with a diagnostic membrane 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.
The 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.
Three FF HP membranes are available with different capillary rise times.
The range of porous materials enhances functionality through surface modification or sorbent addition.
