Flow Cytometry Standards

Polysciences’ Flow Cytometry Standards collection offers a comprehensive suite of microsphere-based calibration and quality-control products designed to support instrument setup, performance verification, and assay standardization in flow cytometry. These standards include count standards like the “Flow Cytometry Absolute Count Standard™,” which delivers highly uniform, fluorescently labeled microspheres at a known concentration for accurate particle counting. They also span size-standards and fluorescence reference kits to validate scatter, fluorescence channels and fluidic stability. The quality of these products aligns with comprehensive instrument-QC programmes and supports high-confidence data generation across research and clinical environments.
