QuantCytes™
QuantCytes™ quantitation controls are precision-engineered synthetic cell mimics designed to quantify antigen molecules per cell and support consistent expression benchmarking across research and development workflows. Each kit includes multiple defined antigen density levels that generate distinct fluorescence intensities, enabling accurate calibration and direct measurement of antibody binding capacity without requiring knowledge of fluorophore molecules per antibody.Measured intensities can be incorporated into the provided Antigen Density Calculator to generate a signal to antigen standard curve, supporting quantitative readouts on cell targets using the same instrumentation and antibody. Unlike biospecimen‑derived materials, QuantCytes™ quantitation controls provide stable antigen presentation and eliminate the variability associated with donor cells. These lyophilized synthetic cell mimics are available in CD19 and can be custom engineered for additional targets to support diverse assay requirements.All QuantCytes™ products are intended for research use only and are not suitable for diagnostic or therapeutic procedures. These products are safe to use in any environment, contain no biohazardous material and require no special disposal.
