Thermo Scientific Pierce Western Blot Signal Enhancer is a two-reagent system for conditioning protein blots after transfer to greatly enhance the effectiveness of primary antibodies and intensify the final detection signal in Western blot experiments.
Features of Western Blot Signal Enhancer:
• Increases protein detection—most protein targets show a three- to 10-fold increase in signal intensity, enabling much less protein to be detected with the same substrate and method • Improves antibody binding—the membrane-treatment reagent exposes and conditions target proteins so that specific antibodies can bind more effectively • Works for nearly any protein—signal enhancement has been demonstrated with targets such as IL-6, p53, NFκB, BRCA1 and EGF • Effective with any substrate—enhances both chemiluminescent (ECL) and colorimetric detection for Western blots • Compatible with any membrane—enhances signal on nitrocellulose and PVDF membrane, regardless of pore size (enhancement is less pronounced with PVDF) • Fast, 15-minute protocol—optimized for a combination of simplicity, speed and signal enhancement for most proteins • Ready-to-use—no formulating or diluting necessary, and the reagents are stable for storage at room temperature
The Pierce Western Blot Signal Enhancer membrane treatment procedure is very simple, takes only 15 minutes and can be added to nearly any existing Western blotting protocol. The result is an increase in the intensity of target protein bands on the Western blot or detection of target proteins at levels that were previously not possible. The product is effective for signal intensification with both chemiluminescent and chromogenic substrates, especially with nitrocellulose membranes.

Frequently asked questions (FAQs)
How can I increase detection sensitivity with SuperSignal West Femto Maximum Sensitivity Substrate?
Treating the nitrocellulose or PVDF membrane with Western Blot Signal Enhancer (Cat. No. 21050) before blocking can boost the chemiluminescent signal of low-intensity bands.
How can I increase detection sensitivity with SuperSignal West Dura Extended Duration Substrate?
Treating the nitrocellulose or PVDF membrane with Western Blot Signal Enhancer (Cat. No. 21050) before blocking can boost the chemiluminescent signal of low-intensity bands.
What is the difference between Western Blot Signal Enhancer and SuperSignal Western Blot Enhancer? Is there any benefit to one versus the other?
The reagents in both kits are different. Western Blot Signal Enhancer (Cat. No. 21050) is a 2-step pre-treatment that occurs before blocking. It basically relaxes the protein on the membrane making the epitope easier to detect. SuperSignal Western Blot Enhancer (Cat. Nos. 46640, 46641) contains a membrane treatment reagent and a primary antibody diluent that increase both signal intensity and sensitivity 3- to 10-fold compared to a detecion performed without it. We have found that SuperSignal Western Blot Enhancer shows much less background while enhancing signal and sensitivity when compared to Western Blot Signal Enhancer.
Can I use the Pierce Western Blot Signal Enhancer on a stripped blot?
After stripping the blot, blocking reagent remains on the membrane so you will get inconsistent results. Therefore, we recommend using the Enhancer only before blocking and the first probing of the membrane.
