LOGOS Fluorescence Signal Enhancer 1

Fluorescence Signal Enhancer 1 is an inhibitor of ATP-dependent fluorescein efflux. By blocking fluorescein from being pumped out of the cell, Fluorescence Signal Enhancer 1 lowers background and increases signal intensity, thereby enhancing the fluorescein signal to-noise ratio. Fluorescence Signal Enhancer 1 is most effective with metabolically active cells in the log growth phase
