Compucyte offers four-laser imaging cytometers

Compucyte has expanded its Igeneration line of imaging cytometers to include four-laser versions of the Icyte, Icys and Icolor systems.

With the option of four excitation lasers chosen from a palette of 405, 488, 532, 561, 594 and 633 nanometres, these analysers are claimed to increase system flexibility when using multiple fluorescent and chromatic dyes.

Mel Henriksen, vice-president of research and development at Compucyte, said: 'The recent development of fluorescent proteins that emit light in the cyan, green, yellow, and orange regions of the spectrum has had a significant impact on multicolour cellular imaging experiments, expanding the range of such experiments that can be undertaken with laser-scanning cytometry technology.

Dr Elena Holden, president and chief executive officer at Compucyte, added: 'The instrument configuration with violet, blue, yellow, and red lasers allows customers to take advantage of the most efficient members in the 'fruit' series of fluorescent proteins while providing full coverage of the chromatic dye absorption spectrum.
