PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting right filter for a Western transfer is be challenging. Traditionally, nitrocellulose filters have been commonly employed, providing moderately cheap price. However, PVDF membranes have significant merits, including better binding potential, minimal protein leakage throughout processing, and higher resistance for harsh reprobing environments. Consequently, even though nitrocellulose stays a viable selection for standard procedures, PVDF is usually the ideal selection in more critical studies.
