SuperSignal™ Western Blot Substrate Bundle, Femto + trial-size Pico PLUS

SuperSignal West Femto Maximum Sensitivity Substrate

Thermo Scientific SuperSignal West Femto Maximum Sensitivity Substrate is an ultra-sensitive enhanced chemiluminescent (ECL) substrate for low femtogram protein level detection by western blot analysis with horseradish peroxidase (HRP) enzyme. It is optimized to detect low abundant and/or difficult to detect targets.

• Sensitivity: low-femtogram (mid-zeptomole)
• Stability: 8-hr working solution stability, 1-year kit stability at 4°C
• Compatibility: nitrocellulose and PVDF membranes
• Signal duration: up to 8 hours
• Recommended primary antibody concentration: 1:5,000–1:100,000 dilution (10–200 ng/mL)
• Recommended secondary antibody concentration: 1:100,000–1:500,000 dilution (2–10 ng/mL)

SuperSignal West Pico PLUS Chemiluminescent Substrate
