Western blotting especially high molecular weight proteins Protein sequencing Amino acid analysis Solid phase assay systems. Both nitrocellulose and PVDF come in typical pore sizes of 0.
Which Membrane Should You Use? Read the next article Transfer Options Wet tank vs. Sample concentration: PVDF membranes have a higher protein binding capacity than nitrocellulose. Membrane integrity: PVDF membranes are less fragile than nitrocellulose and generally a better choice for experiments that require stripping and re-probing of the membrane.
Pore size: Both PVDF and nitrocellulose Western blotting membranes are commonly available in two different pore sizes, 0. Transfer buffer conditions: Transfer buffer must contain methanol when using nitrocellulose membranes. In addition to these, the nitrocellulose membrane is difficult to strip and reprobe while the PVDF membrane is easy to strip and reprobe due to its higher hydrophobicity.
Nitrocellulose membrane is the type of membrane important in western blot. However, it has a comparatively low protein-binding capacity and sensitivity. It also produces a lower background. Moreover, it is mainly used in the separation of high molecular weight proteins. The PVDF membrane is the other type of membrane used in western blot for the separation of high molecular weight proteins. Moreover, this membrane has a comparatively higher protein-binding capacity and sensitivity.
However, it produces a higher background. Therefore, the main difference between nitrocellulose and PVDF membrane is their protein-binding capacity and sensitivity. The ProteinMan.
