Choosing the Right PVDF Membrane for Your Western Blot
Selecting a best PVDF membrane can be essential for successful Western blots. Evaluate aperture size; bigger pore dimensions tend to be higher molecular masses, while smaller pore sizes provide enhanced resolution for little proteins. Furthermore, assess the filter's binding capacity; increased attachment is stronger signal measurement, particularly during dealing with minimal concentration proteins. Finally, compare different makes and their particular guidelines for best operation.
