GRADE & PURITY Ex:498nm ? Fluorescence excitation maximum at 498 nm — the wavelength of light that best excites this fluorophore. Match it to your instrument's laser or filter set for the strongest signal. Em:526nm ? Fluorescence emission maximum at 526 nm — the wavelength this fluorophore emits after excitation. Use it to pick the right detection filter and avoid channel cross-talk. ≥98%
