- The light intensity of the LED (LED-intensity) and the signal amplification (Gain) can be adjusted in a wide range. The table suggests initial values, which can be optimised for specific applications.
- The settings depend on the concentration of the fluorophore, which vary between different applications. Therefore, only recommendations for specific fluorophore concentrations are given. In the Amplex® UltraRed assay the fluorophore is formed during the experiment.
- The recommendations apply to experiments at 37 °C. The Fluorescence intensity increases strongly at lower temperatures. Then the light intensity is reduced to avoid off-scale signals.
- The light intensity of the LED (LED-intensity) and the signal amplification (Gain) can be adjusted in a wide range. The table suggests initial values, which can be optimised for specific applications.
