PVDF Western Blotting Membranes are hydrophobic, microporous, polyvinylidene difluoride (PVDF) membranes with a pore size of 0.2μm. The PVDF Western Blotting Membranes are ideal for western and dot blots. The high binding capacity, high mechanical strength, and chemical resistance of the PVDF membrane makes it specifically useful for protein blotting. The combination of strong sample retention and low background binding generates excellent signal-to-noise ratios in colorimetric and chemiluminescent detection. The primary binding mechanism includes electrostatic and hydrophobic nature.
