MilliporeSigma adds a green laser to its flow cytometers

Life science company MilliporeSigma has expanded its line of Guava flow cytometers to feature a high-power modulated green laser, adding to the violet, blue and red lasers already included in the device. The addition of the 532 nm laser expands the detection capabilities of the Guava easyCyte instrument line to enable simultaneous detection of multiple fluorescent proteins.

Since the discovery and isolation of the gene-encoding proteins responsible for biological fluorescence, fluorescent proteins (FPs) have changed life science research. Both mutation of the original green FP and discovery of naturally occurring proteins emitting elsewhere in the spectrum have resulted in FPs of many colours.

The Guava easyCyte green laser variant allows users to analyse heterogeneous biological tissues and systems in a single experiment. Improved optical configurations are said to meet the needs of any lab, research discipline or individual application and permit a small benchtop footprint. This gives users reduced buffer and sample volumes and reduces waste when compared with sheath-based flow cytometers, according to the company.
