Spectral flow cytometry improves flow cytometry panels by resolving the full emission spectra of individual fluorophores, allowing greater flexibility to incorporate more fluorochromes when designing multicolor panels. Additionally, the spectral approach captures the autofluorescence of a sample or cell population (e.g., macrophages, which are highly autofluorescent) that can be considered during unmixing for improved downstream analyses. As the increased complexity of macrophage heterogeneity unravels in the scientific community, it is crucial to obtain high-dimensional data at the single-cell level to resolve these populations.
