## TL;DR

Cytek Biosciences makes the Aurora and Northern Lights full-spectrum flow cytometers, which read the whole emission spectrum of every dye so forty or more markers can be measured on each cell, used in immunology, cell therapy development and clinical haematology.

## Summary

Cytek Biosciences, listed on Nasdaq since 2021, pioneered full-spectrum cytometry: instead of one detector per dye, arrays of detectors capture each cell's complete emission spectrum and software unmixes the dyes, allowing very high-parameter panels on a compact instrument. Its Aurora, Northern Lights and Aurora CS sorter are used to characterise CAR-T and TIL products, profile immune responses to checkpoint inhibitors and, in clinical configurations, for leukaemia immunophenotyping. OnCo links it to flow cytometers.
