Westran S PVDF is a 0.2 μm pore size hydrophobic membrane designed specifically for protein sequencing applications. The small pore size of this membrane eliminates ‘blow-through’ and increases protein binding over a wide range of molecular weights.
Protein binding capacity (over 200 μg/cm2) for easy signal detection
Chemical resistance needed for N-terminal sequencing
High protein retention even after harsh wash steps
Maximum capture of proteins during transfers minimizing sample loss
0.2 μm pore size for higher surface area, resulting in better binding of low molecular weight proteins
