Spectral Flow Cytometry Capabilities

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 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.

Advantages of spectral flow cytometry

More detection

5 lasers with 64 fluorescence detectors

Greater Flexibility

Use of a wide array of new fluorochrome combinations without the need to reconfigure optical filters

Outstanding Sensitivity

Unmixing of fluorochrome with close emission peaks
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.

4T1-Luc2-1A4 tSNE analysis Plotting traditional gating populations over the tSNE map allows the visualization of shifts in the expression of any panel markers (population shifts) between treatment groups

Big insights from small samples

Our expert flow cytometry team can perform deep immunophenotyping investigation of your in vivo study to capture shifts that occur in the immune response triggered by test agent treatment. Below is a list of our standard spectral panels. These panels have the capacity for additional markers to be added and completely custom panels can be developed for your assay needs.
