Troubleshooting Common PVDF Membrane Western Blot Issues
Successfully producing well-defined Western blot outcomes with PVDF membranes often necessitates careful assessment of various frequent issues. Weak antibody detection can arise from suboptimal antibody concentration, lacking migration, or non-specific binding. Excessive noise may indicate excessive antibody reaction period, poor blocking, or occurrence of surfactant interference. Transfection error is frequently associated to incorrect setup of the apparatus or deficient saturating of the membrane prior to use. Finally, problem re-analyzing the filter can result from fixed antibody binding so correct stabilization is crucial after transfer but preceding re-use.
