Why Choose NeoPRO Atto Western ECL Substrate?
Superior Performance vs. Leading Substrates
NeoPRO Atto Western ECL Substrate exhibits superior performance in the reported comparisons with NeoPRO Femto PLUS, SuperSignal™ West Femto, Amersham™ ECL Select™, and Clarity Max™.
Extreme Sensitivity and Wide Linear Range
With R² > 0.99, it offers a wide linear dynamic range and a signal-to-noise ratio up to 10-fold higher than the leading ECL substrates tested, supporting accurate interpretation of even faint bands.
Save Precious Samples and Antibodies
Its high signal intensity enables equivalent signal with one-eighth of the protein amount required with Amersham™ ECL Select™, and comparable performance with one-tenth of the primary antibody amount used with Clarity Max™ in the reported experiments.
Shorten Exposure Time
It delivers signal intensity and sensitivity comparable to Clarity Max™ with a 10-second exposure instead of 5 minutes in the reported comparison, saving time and improving productivity.
High Reproducibility
In a simplified multiwell assay, substrate performance is assessed independently of sample loading, transfer efficiency, blocking, and antibody performance. Reported variability in triplicate is below 20%.
