BrightLine® FRET filter set, optimized for Blue & Green Fluorescent Protein and other like fluorophores

Semrock Part Number: FRET-BFP/GFP-B-NTE

IDEX Part Number: S-001476  /

Semrock

This four-filter set is specially designed to achieve high-performance fast FRET (Fluorescence Resonance Energy Transfer) imaging for blue donor fluorescence and green acceptor fluorescence. FRET measurements using wide-field microscopy are challenging – using the best possible filters can make a significant difference. These filter combinations provide excellent brightness and signal-to-noise ratio while minimizing the undesirable donor-acceptor crosstalk.
