In contrast to traditional flow cytometers which use optical filters to deconvolute fluorescent signals, the Aurora measures the ‘spectral fingerprint’ of different fluorochromes and is able to ‘unmix’ the signals from a multi-stained sample i.e. two fluorochromes which could not be used together using a traditional cytometer can often be identified as separate signals by the Aurora. Our three-laser Aurora measures fluorescence in 42-channels of detection across the three avalanche-photodiodes (APD) detector arrays. APDs offer greater sensitivity for fluorochromes which fluoresce at longer wavelengths e.g. PE-Cy7.

The Aurora also is able to subtract cellular autofluorescence, greatly aiding the analysis of cellular markers in highly autofluorescent cell types or after techniques which increase autofluorescence such as intracellular cytokine staining – something not possible with traditional flow cytometers.

The Aurora has 58-channels of fluorescence detection across four APD detector arrays and is equipped with a UV (355nm, 20mW), violet (405nm, 100mW), blue (488nm, 50mW) and red (638nm, 80mW) laser. The lasers have a flat-top beam profile with a narrow vertical beam height, optimised for the detection of small particles. Our Aurora has 2 additional detectors in the infra-red region of the spectrum off the blue and red lasers and as such, is the only one of its kind in Europe.
