SpectraComp® Flex XT

SpectraComp® 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 positive and negative fluorescence peaks after staining with fluorescently conjugated antibodies. Each control captures antibodies from mouse, rat and hamster sources, supporting broad panel compatibility and diverse fluorophore selections. With high fluorescence response and cell like autofluorescence, SpectraComp delivers superior signal to noise resolution and reduces errors associated with spectral overlap. Its consistent fluorescence intensity and physiologically relevant scatter characteristics outperform traditional polystyrene based beads while preserving the behavior of cell based controls. SpectraComp is suitable for spectral unmixing or conventional compensation and is supplied as a single vial containing both positive and negative capture mimics for streamlined workflows. These controls require no special handling or safety precautions and have been validated on analytical flow cytometers for dependable performance in daily QC, assay development and high parameter panel design. Benefits: Unparalleled high fluorescence response (greater than 10e5 MFI on most bright fluorochrome) Conveniently works with multiple species of antibodies: mouse, rat, and hamster Exceptional performance in spectral analysis and unmixing Compatible with violet and UV fluorochromes Cell-like autofluorescence for superior signal-to-noise resolution Resources: SpectraComp® Application Note Technical Data Sheet Safety Data Sheet Certificate of Analysis Poster: Spectral Cytometry Reference Controls: The Search for the Perfect Particle Publication: Jensen, HA, Kim, J. iCoreDrop: A robust immune monitoring spectral cytometry assay with six open channels for biomarker flexibility.

SpectraComp® eGFP Controls are precision engineered multi level fluorescent cell mimics designed to support accurate unmixing, compensation and calibration of GFP signals in multiparameter flow cytometry workflows. These controls present eGFP protein on the particle surface and provide negative, low, medium and high fluorescence populations that mimic the performance of eGFP expressing cells. Each positive population contains a defined number of eGFP molecules, generating distinct fluorescence intensity levels for reliable benchmarking and reference signal generation. With consistent fluorescence intensity, cell-like autofluorescence and the high performance characteristics shared across all SpectraComp Controls, SpectraComp eGFP delivers dependable signal resolution and reduces errors associated with spectral overlap. The kit includes four liquid dropper vials containing separate negative, low, medium and high populations, supporting flexible experimental setup and streamlined workflow integration. These controls are suitable for spectral unmixing, conventional compensation, fluorescence calibration and assessment of transfection efficiency. SpectraComp eGFP requires no special handling or safety precautions and has been validated on analytical flow cytometers for dependable performance in daily QC, assay development and high parameter panel design. Unit Size: 25 tests of each populationPackaging: separate neg, low, med, and high populationsProduct format: 4 liquid dropper vialsApplication: Unmixing, compensation, calibration, or transfection efficiency control Benefits: State-of-the-art controls designed using actual eGFP protein (excitation peak at 488 nm and max emission at 507 nm) Three mean fluorescence intensity levels (low, medium, and high) Consistent fluorescence signals for reliable performance Cell-like autofluorescence for workflow efficiency Resources: Technical Data Sheet Safety Data Sheet Certificate of Analysis
