Troubleshooting Common Issues with PVDF Membranes in Western Blotting
PVDF membrane are commonly considered reliable for WB transfer, however, multiple problem-solving processes may are required when problems arise. Regularly, substantial background, low signal, or uneven transfer can be caused to reasons like improper filter preparation, inadequate blocking solution, or poor protocol. Careful focus to all step of the protocol, such as checking buffer acidity and ion concentrations, is essential for obtaining ideal data. Additional examination regarding transfer efficiency utilizing methods such as Ponceau dye staining procedure may help pinpoint transferring faults.
