Spectral Flow Cytometry Capabilities

Full spectrum technology has taken flow cytometry to the next level of performance and flexibility delivering deep immunophenotyping capabilities with outstanding resolution.
  • Spectral unmixing for deeper immunoprofiling

  • Intuitive panel design for customizing panels

  • Autofluorescence extraction for improved sensitivity and resolution

How does spectral flow cytometry work?

Spectral flow cytometry offers unique optical collection and analytical capabilities enabling the use of a wide range of fluorochrome combinations without reconfiguring the system for each application, resulting in exceptional sensitivity with simple and intuitive operations. Full spectrum signatures are generated for each fluorochrome bound to cellular markers that are used to identify different cell types. Different signatures present in a multicolor sample are then unmixed to allow the use of fluorochromes with close emission peaks in the same sample. This expansion in fluorochrome options and panel size potential, along with the vacuum-powered fluidics system, makes the Cytek® Aurora spectral flow cytometry particularly suitable for studies where unique biomarker signatures are sought or sample availability is limited.

In a conventional flow cytometer, pacific blue and brilliant violet 421 (BV421) cannot be used together as the spectral signatures are too similar.


In a conventional flow cytometer, pacific blue and brilliant violet 421 (BV421) cannot be used together as the spectral signatures are too similar. In spectral flow cytometry, pacific blue and BV421 have enough distinctions (a complexity index of 0.78) in their spectral signatures to be used in combination.

  • Use of autofluorescence extraction to improve data clarity

More colors

Detection of up to 40 different cell types/targets in the same multicolor sample

High Value System

Larger datasets generated from smaller sample sizes

Advanced technology with full analytical compatibility and familiar workflows

Spectral flow cytometry offers several advantages over conventional flow cytometry and at the same time is amenable to complex analyses of multiparameter flow cytometric data such as the t-Distributed Stochastic Neighbor Embedding (tSNE) analysis that allows for an unbiased analysis of all markers in the panel to help discern phenotypic changes within cell subsets that would otherwise go undiscovered. Spectral flow cytometry has all the capabilities of conventional flow cytometry, follows the same workflow and shares the same requirements, while expanding its functionalities.

    Spectral flow cytometry capabilities FAQs

    Spectral flow cytometry presents unique advantages over conventional flow cytometry in the following scenarios:

    • When sample availability is limited
    • When deep immunoprofiling is needed to analyze up to 40 targets
    • When analyzing sample types with high autofluorescence such as lung tissue
    • When unique biomarker signatures are sought
    • When particles as small as 100 nm need to be analyzed

    We have spectral immunophenotyping panels for both human and mouse samples:
