SpectraComp® controls are precision-engineered single-stain cell mimics that streamline spectral unmixing and compensation in multiparameter flow cytometry workflows. Designed to behave like real cells, they deliver reliable positive and negative populations for confident panel design and assay development.
Optimized for spectral and conventional compensation
SpectraComp® controls are formulated to support both spectral unmixing and traditional compensation strategies in analytical flow cytometry. Each vial contains a mixture of positive and negative capture mimics, simplifying setup and reducing preparation steps. High fluorescence response combined with cell-like autofluorescence enhances signal-to-noise resolution and minimizes errors caused by spectral overlap.
Broad antibody and fluorophore compatibility
Every control is engineered to capture antibodies derived from mouse, rat, and hamster, enabling flexible panel design across diverse fluorophore selections. Matching by species reactivity and format ensures that controls align closely with experimental samples, supporting accurate viability modeling and robust data quality.
Consistent, cell-like performance
SpectraComp® controls provide physiologically relevant light scatter characteristics and consistent fluorescence intensity, outperforming traditional polystyrene bead-based reagents while preserving the behavior of cell-based controls. Lot-to-lot uniformity supports reproducible results across experiments without special handling or safety precautions.

Compensation and spectral unmixing using Slingshot SpectraComp as reference controls
This application note evaluates Slingshot SpectraComp® synthetic cell-like controls for compensation and spectral unmixing in flow cytometry. Discover how across two studies, SpectraComp controls demonstrated spectral profiles closely matching cells, and were interchangeable with cell-based controls for most markers, improving background reduction and unmixing accuracy. The results highlight a practical alternative to traditional compensation beads, particularly for complex multicolor panels and limited sample types.
