The SuperSignal™ West Dura Extended Duration Substrate is a sensitive, luminol-based enhanced chemiluminescent substrate for detecting horseradish peroxidase (HRP) on immunoblots. SuperSignal West Dura Substrate enables mid-femtogram detection of antigen by oxidising luminol in the presence of HRP and peroxide. This reaction produces a prolonged chemiluminescence which can be visualised on X-ray film or an imaging system. Optimal signal intensity and duration can be attained with appropriate primary and secondary antibody dilutions.

• Enhanced chemiluminescent substrate with high sensitivity and long signal duration for horseradish peroxidase (HRP)
• Femtogram-level sensitivity
• Less antibodies usage - up to 25 to 50 times more blots than possible with other chemiluminescent substrates
• Intense signal is generated immediately and is easily detected on film or chemiluminescent imaging systems
• Light emission stable for up to 10 times longer than other chemiluminescent substrates, allowing multiple exposures for publication-quality blots
