Fluorobind membranes are based on PVDF-type chemistry and show an excellent protein binding capacity. They are not only suitable for all standard applications in protein analysis, but as well for special applications like fluorescence detection and protein sequencing. The pore size of 0.2 µm is ideal for blotting of proteins of lower molecular weight and of peptides, but can as well be used for larger proteins. The membranes feature a high sensitivity with low background in all common detection systems. The high mechanical stability facilitates handling and allows multiple stripping of the membrane and harsh washing conditions.
