PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting best filter for your Western blot may seem challenging. Historically, nitrocellulose filters have been generally applied, giving relatively inexpensive cost. However, PVDF membranes possess important merits, like superior attachment capacity, less molecule escape during blotting, and greater resistance during harsh reprobing conditions. Thus, even though nitrocellulose stays an viable choice to routine uses, PVDF is frequently a ideal option in complex critical research.
