PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting right filter for your Western blot is be challenging. Initially, nitrocellulose sheets were commonly applied, offering moderately inexpensive price. However, PVDF filters possess important benefits, such as enhanced binding potential, reduced substance loss during processing, and greater durability during harsh re-blotting situations. Therefore, even though nitrocellulose stays the feasible option in routine procedures, PVDF is usually a favorable selection to greater critical experiments.
