SpectraComp® XT controls are precision engineered single stain cell mimics designed to optimize spectral unmixing and compensation in multiparameter flow cytometry workflows. These controls mimic the staining performance of real cells and provide clear positive and negative fluorescence peaks after staining with fluorescently conjugated antibodies.
As with all SpectraComp controls, SpectraComp XT delivers high fluorescence response and cell-like autofluorescence to provide superior signal to noise resolution and reduce errors associated with spectral overlap. The consistent fluorescence intensity and physiologically relevant scatter characteristics of SpectraComp controls outperform traditional polystyrene based beads and support reliable spectral unmixing or conventional compensation across instruments and platforms. SpectraComp XT expands species compatibility by capturing antibodies from mouse, rat, hamster, rabbit and human sources, supporting broad panel design and diverse fluorophore selections. Compatible with violet, UV and tandem dyes, these controls are supplied as a combined positive and negative population for streamlined workflow integration.These controls require no special handling or safety precautions and have been validated on analytical flow cytometers for dependable performance in assay development and high parameter panel design.

Questions
SpectraComp uses a 3D hydrogel matrix that physically mimics the size, scatter profile, and autofluorescence of real leukocytes. Unlike solid-core polystyrene beads, SpectraComp produces cell-matched spectral signatures, critical for accurate spectral unmixing. This eliminates the UV/violet autofluorescence artifacts common with polystyrene-based controls.
