The Pierce Reversible Protein Stain Kit for Nitrocellulose Membranes is a rapid and sensitive alternative to Ponceau S stain for protein detection on nitrocellulose membranes after transfer from polyacrylamide gels.

Features:
Sensitive—high-avidity, total-protein stain; lower limit of detection equals 25 to 50 ng per band
Specific—detects only protein; does not bind or interact with other electrophoresis or sample components
Protocol—stain in less than five minutes; completely erase and reverse staining in less than 15 minutes
Stability—components are stable at room temperature, saving refrigerator space and eliminating equilibration steps

This kit for membrane staining uses a nondestructive, reversible, reliable, and sensitive method to stain and detect proteins on nitrocellulose membranes. The lower limit of detection with this method is 25 to 50 ng per band (at least five times more sensitive than traditional Ponceau S staining). The stain has minimal nonspecific interactions with the membrane surface and protein-transfer reagents. The staining protocol is simple and quick and results in turquoise-blue bands that do not fade and are easily photographed for future reference. The stain can be easily reversed in less than 15 minutes. Subsequent western blot detection is unaffected because the stain does not alter the protein and is completely removed. In addition, the stain is compatible with N-terminal sequence analysis of proteins excised and eluted from membrane.
For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

How can I increase the signal intensity when I am using SuperSignal West Femto Maximum Sensitivity Substrate?

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.
