This filter set is designed for use with Cy5™ and Alexa Fluor 647 and works well with ATTO 643, ATTO 647 and other Red fluorophores. The Avant™ filter set family delivers significant increases in fluorescence performance for small Stokes Shift fluorophores compared to standard filter sets. Steep spectral edges and high complementary OD blocking maximize signal while maintaining low bleedthrough and high signal to noise ratio. The new Precise Edge Placement capability ensures every filter set delivers consistent performance.
