PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting appropriate membrane for the Western analysis can appear difficult. Initially, nitrocellulose sheets were widely used, offering moderately inexpensive value. However, PVDF membranes possess notable advantages, like better attachment ability, less protein leakage during blotting, and greater durability during harsh re-blotting situations. Consequently, while nitrocellulose remains a feasible selection for routine applications, PVDF are frequently a preferred option for greater demanding experiments.
