The pE-340fura is a bespoke LED Illuminator for Fura-2 ratiometric calcium imaging. The calcium imaging light source utilises the successful pE-300 Series platform, and also supports everyday fluorescence microscopy in a compact and affordable package.




The 340 nm and 380 nm LED illumination system provides the optimum excitation wavelengths for Fura-2-based calcium imaging, allowing high-precision, stable, high-throughput imaging with video-rate time resolution.
High-speed acquisition

Until recently, the response time of illumination systems for Fura-2 imaging has been limited to milliseconds due to mechanical switching of the wavelengths in arc lamp and monochromator systems.  However, the new pE-340fura can be controlled via convenient BNC TTL connections for precise illumination control in as little as 20 microseconds.

Improved cell viability and cost

Using the new pE-340fura LED Illumination System, less Fura-2 dye can be loaded into the cells whilst still maintaining the same measured calcium concentration and good signal-to-noise ratio.  The reduction in required dye not only improves cell-viability due to reduced dye toxicity, but also results in a cost reduction per experiment.

Improved signal to noise

Work by Sandrine Prost et al., from the University of Edinburgh, has shown that with independent wavelength controllable LED sources, signal-to-noise is dramatically improved over bulb systems and even over some available white broad-spectrum LED sources.




Features-

  • Dedicated 340 nm and 380 nm outputs for Fura-2 ratiometric calcium imaging
  • Broad white output (435 nm – 645 nm) for imaging standard fluorophores
  • Microsecond switching (340/380) for capturing high-speed events
  • Stable LED illumination minimises noise below that of experiment, reducing false positives and increasing precision.
  • Higher signal-to-noise gives cleaner images and data whilst requiring less Fura-2 dye, reducing toxicity and costs
  • UV optimised optics delivers maximum irradiance on standard microscope configurations
  • Individual channel triggering via TTL in microseconds
  • Removable inline excitation filter holders: no moving parts for fast acquisition
  • Sequence Runner – sequenced excitation from a single TTL-out
  • Individual channel selection controls the level of excitation of each dye independently on a multi-stained sample
  • Compatible with most imaging software for integrated control with imaging set up
  • Precise irradiance control in 1% steps (0-100%): no ND filters required
Convenience
  • Specify for existing single and multi-band filter sets: no need to buy new filters
  • Simple to fit, simple to use: no alignment, a once only adjustment
  • Wide range of microscope adaptors: fits most microscopes
