WesternLumaxLight  Enhance HRP substrate

Quantitative chemiluminescent Western blotting

WesternLumaxLight  Enhance is formulated to take full advantage of the linear dynamic range of CCD imagers.It provides high sensitivity

 to detect low abundance proteins, and does not exhibit substrate depletion with high abundance proteins, so has a larger linear dynamic 

range than other commercially available substrates.A signal linear with respect to protein concentration over 3 orders of magnitude 

provides the ability to accurately quantify and compare protein amounts in your samples.

WesternLumaxLight  Enhance chemiluminescent substrate sets the bar for both sensitivity and quantitative ability. Specially developed for CCD imaging, WesternBright Quantum produces a strong, long-lasting signal with extremely low background, perfect for detecting low abundance proteins. Since it does not exhibit substrate depletion at high protein loads, WesternBright Quantum provides the largest dynamic range of any chemiluminescent substrate for the most quantitative chemiluminescent Western experiments.

Figure 1. WesternLumaxLight  Enhance  provides a larger linear dynamic range than Amersham ECL or ECL Plus (GE Healthcare) or SuperSignal West Dura (Thermo Scientific). Identical Western blots containing serial dilutions of transferring were probed with a rabbit-anti-transferrin primary antibody and a goat-anti-rabbit secondary antibody conjugated to horseradish peroxidase. The blots were incubated with chemiluminescent substrates as recommended by each manufacturer. All blots were imaged simultaneously for 2 minutes on a CCD imager and display parameters are identical across all images shown. Band intensities were plotted and a best fit linear regression conducted for each substrate. WesternLumaxLight  Enhance shows the largest linear dynamic range out of all four substrates with the highest R2 value. Bands that fall on the linear part of the curve for each substrate are indicated in the image.

 

Figure 2. WesternLumaxLight  Enhance produces the most stable chemiluminescent signal. Blots detected using WesternLumaxLight  Enhance or one of three other chemiluminescent substrates were re-imaged at several times over a 10 hour period. The intensitiy of one band is plotted. 60 minutes after substrate incubation, WesternLumaxLight  Enhance retains 70% of its initial signal strength, while the competition decays to 5% or less.

CUSTOMER FEEDBACK

We really like the Quantum kit. We use it instead of the ECL Plus kit because the signal lasts longer and doesn‘t burn out as frequently.

We love the Quantum. In our hands I’d say it’s 2-5x better than ECL Prime.
