Polyvinylidene Fluoride Filter vs. Nitrocellulose : What are Best?
When selecting a filter for filtration applications, an important decision revolves around the substance: namely PVDF (Polyvinylidene Fluoride membrane ) or NC. Nitrocellulose provides excellent protein attachment capabilities, which makes it appropriate for processes including western blotting . However , PVDF membranes generally exhibit greater chemical resistance , leading to more for rigorous conditions or if using harsh solvents .
- PVDF membrane : High chemical resistance .
- Nitrocellulose filter: Good macromolecule binding.
