Thermo Scientific SuperSignal West Dura Extended Duration Substrate is a luminol-based enhanced chemiluminescence (ECL) HRP substrate with stable light output for mid-femtogram-level detection with CCD-based imagers.

Features of SuperSignal West Dura Extended Duration Substrate:

ECL—enhanced chemiluminescent substrate with high sensitivity and long signal duration for horseradish peroxidase (HRP)
24-hour signal duration—light emission is stable for 10 times longer than with typical ECL substrates; acquire multiple exposures to obtain publication-quality blot images
Great sensitivity—provides detection of mid-femtogram levels of target proteins
High intensity—immediate, stable signal generation provides easy detection via film or cooled CCD imaging systems
Stable reagent—24-hour working solution stability; 1-year kit stability at room temperature
Less antibody usage—works best with dilute antibody concentrations:
• 20ng to 1.0 µg/mL primary antibody (1:1000 to 1:50,000 dilution from 1 mg/mL stock)
• 4 to 20 ng/mL secondary antibody (1:50,000 to 1:250,000 dilution from 1 mg/mL stock)
