PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting right sheet for your Western analysis is be challenging. Historically, nitrocellulose membranes have been generally applied, offering relatively inexpensive cost. But, PVDF check here sheets exhibit significant benefits, like better attachment ability, less substance escape during transfer, and higher resistance for stringent reprocessing conditions. Thus, even though nitrocellulose exists the viable selection in standard uses, PVDF are often the preferred option for greater demanding experiments.
