Chroma Technology Corp. Widefield (non-laser) Microscopy Ratiometric Filter Sets 79001 ET - Fura 2

This series of filter sets is designed for use with various Indicator Dyes which exhibit multiple absorption or emission peaks to facilitate ratiometric imaging. This allows for the detection and quantification of ratiometric signal intensities, which may indicate changes in the concentration of ion(s) of interest, changes in pH or changes in membrane potential. Sets with multiple excitation filters require the use of a filter wheel to alternate between the various excitation wavelengths. Sets with multiple emission filters require the use of either emission filter wheels or image-splitters.
