PVDF Western Blotting Membrane

PVDF membrane is ideal for western blotting application. Cobetter provides high binding capacity Hydrophobic PVDF membrane with the pore size of 0.2um for western blots, dot blots, protein sequencing, and amino acid analysis. 

Strong protein adsorption capacity and signal low background make hydrophobic PVDF membrane perform better than other materials. Especially under rigorous conditions, such as when organic, acid and alkali solvent occurs. PVDF has better sensitivity and less brittle than nitrocellulose as well. 

In addition, PVDF membrane is reusable without a loss of sensitivity or increased background.  

Comparison of performance between Cobetter membrane and other brands. 


  • High mechanical strength, hard to be broken and be curly, good heat resistant and reusable
  • High protein binding ability, high sensitivity, low background
  • Broad chemistry compatibility
