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.
This set is mounted in an Evident Scientific (Olympus) OMF Fluorescence Filter Holder, which is compatible with the AX (AX70), BX2 (BX41, BX50, BX51, BX60, BX61, BX50/51WI, BX60/61WI), and IX2 Series (IX50, IX51, IX70, IX71, IX81) of Evident Scientific (Olympus) microscopes.
