Cellulose nitrate (CN) membranes are recommended for filtering solutions where protein binding is not a concern. I'm curious about how the chemical differences affect their properties as a membrane material. Polyethersulfone (PES) is ideal when fast flux is needed to filter volumes quickly, and is also low-protein-binding. Immobilon PVDF membranes are offered in four types, each optimized for a different protein blotting application. An incompatibility here can lead to sample solutes unexpectedly being retained by the filter (protein binding) or unwanted solutes being released into a sample (extractables) from the filter material or housing.
