PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting best filter for a Western transfer may be challenging. Traditionally, nitrocellulose filters had been generally employed, giving comparatively cheap value. However, PVDF membranes possess important advantages, such as superior binding capacity, reduced protein leakage during processing, and higher resistance during harsh re-blotting situations. Consequently, although nitrocellulose stays a workable option in typical applications, PVDF are often a ideal choice in complex essential studies.
