Troubleshooting Common PVDF Membrane Western Blot Issues
Successfully achieving distinct Western blot results with PVDF membranes often necessitates careful evaluation of various frequent problems. Weak antibody presence can stem from suboptimal antibody dilution, lacking migration, or non-specific adhesion. High signal may indicate too much antibody incubation duration, poor blocking, or presence of surfactant pvdf membrane for western blot problems. Transfer defect is frequently related to faulty configuration of the gel or lacking soaking of the filter prior to use. Finally, trouble re-examining the membrane can lead from irreversible antibody attachment so appropriate crosslinking is crucial after transfection but before re-examination.
