Fluorophore Databases

Use these spectral databases to check the behaviour of your fluorescent probe of choice with respect to the laser line, or the bandwidth of the filter block, used to illuminate it, and the bandwidth of the emission filter used to collect the emitted signal into the CCD or PMT.
