Real-World Testing: Putting Whatman Protran Nitrocellulose Membrane Filters, Whatman 10402506 Discs, Pack of 100 to the Test
First Use Experience
I initially tested the Whatman Protran Nitrocellulose Membrane Filters in a Western blotting experiment to transfer proteins from an SDS-PAGE gel to the membrane. I performed the transfer using a standard wet transfer apparatus in a cold room. The membranes were easy to handle and didn’t tear or crack during the blotting process.
The membrane performed well under standard transfer conditions and at low temperatures, providing uniform protein binding. The transfer was even and efficient, as visualized by Ponceau S staining. There were no unexpected issues during the first-time use. The transfer process worked like a charm!
Extended Use & Reliability
After several weeks of using the Whatman Protran Nitrocellulose Membrane Filters in various blotting experiments, I can confidently say that they hold up remarkably well. The membranes maintain their integrity, and I have observed consistent transfer efficiencies across multiple experiments.
There are minimal signs of wear and tear. The Whatman Protran Nitrocellulose Membrane Filters show no degradation even after being stored properly for weeks. Maintenance is straightforward as the membranes require only standard washing and blocking procedures commonly used in blotting protocols. Compared to the membranes we were using before, the Whatman membranes demonstrate superior performance and greater reliability.
