PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting right filter for the Western analysis may seem tricky. Initially, nitrocellulose filters had been commonly used, giving moderately cheap value. However, PVDF sheets possess important benefits, including superior attachment capacity, less protein loss throughout blotting, and increased durability for stringent reprobing environments. Therefore, while nitrocellulose stays the feasible option for routine procedures, PVDF is often the favorable selection to greater demanding studies.
