The following are possible causes for weak signal intensity:
- Low level of protein transferred from the gel to the membrane. This is particularly true for high molecular weight proteins. Reversible Protein Stain Kits for Nitrocellulose and PVDF membranes (Cat. Nos. 24580 and 24585, respectively) may be used to stain the bands on the membrane to indicate transfer efficiency.
- Over-diluted primary and secondary antibody probes. We suggest using the recommended dilution for the antibody probes for each substrate. More sensitive substrates will require a more dilute antibody solution.
- Short substrate incubation time. For best results, incubate the membrane for 5-15 min in the SuperSignal substrate.
