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

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

IDEX Part Number: S-001474  /

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.

TopicDescription
Cleaning Optical FiltersInstructions for cleaning hard coated optical filters
Filter ReliabilityCompares the performance and reliability of hard coated filters to traditional soft-coated filters and provides information about the testing standards for Semrock filters
Working with Optical Density Tables to describe the relationship between OD and transmission with tips for quickly calculating OD
What is Pixel Shift, and how does the Semrock ZERO option help? Why Pixel Shift degrades multicolor fluorescence imaging performance, and how the ZERO™ option mitigates this for Avant and BrightLine filter sets.
Optimized – Filter set is specifically optimized for that fluorophore.
Compatible – Should result in nearly ideal performance in most situations.
Acceptable – Actual performance is dependent on specific experimental conditions.
