Semrock Filter Set: FURA2-C

BrightLine® single-band multi-exciter filter set, optimized for FURA2 and other like fluorophores

This four-filter BrightLine fluorescence set is specially designed to achieve high-performance fast ratiometric imaging of Ca2+ using Fura-2 as an indicator. The carefully optimized excitation filters provide superb balance of free and saturated Ca2+ signals, while minimizing the crosstalk and noise, resulting in the most accurate ratiometric measurements. The high signal throughput of the filter set permits reliable Fura-2 (Ca2+) measurements, even when using light sources of relatively limited ultraviolet output. Independent laboratories have measured this set to have 2-4X the free and saturated signals as compared with filters from the leading competitor.

Individual filters and filter sets (no cube):
These filters sets contain individual filters. For filter sets already mounted in a holder/cube, scroll down to see complete mounted sets with cubes.
