PVDF Membranes vs. Nitrocellulose: Which is Best for Western Blot?
Selecting best sheet for the Western transfer is appear challenging. Historically, nitrocellulose sheets have been widely employed, providing comparatively cheap value. Nevertheless, PVDF sheets exhibit notable advantages, like better binding capacity, less molecule escape throughout blotting, and increased durability during demanding reprocessing environments. Thus, while nitrocellulose exists a viable choice in routine uses, PVDF are frequently a ideal selection for complex critical studies.
