Fluorospheres & Quality Control

Comprehensive QC solutions and versatile support reagents for your flow cytometry analysis. 

Daily calibration and standardization of flow cytometry systems are critical components of the daily QC process. Our product portfolio helps to ensure that the system is optimized and ready to produce accurate and precise results. 

The Cyto-Comp Cell Kit provides lyophilized human lymphocytes that are used to establish and monitor color compensation where multi-color flow cytometry assays are performed. Stem-Trol Control Cells are positive control cells for absolute CD34+ stem cell enumeration. Our wide variety of assay and staining controls, as well as full process controls, are powerful tools for clinical and clinical research laboratories. 

Viability dyes to ensure meaningful results and support reagents, like buffers, cleaning and sheath fluids, complete the workflow solution offering from specimen to result. 
  • Optimal flow cytometry data using our reagents for instrument setup, quality control and absolute counting.
  • Comprehensive portfolio of viability dyes.
  • Cleaning reagents, buffers and sheath fluids for enhanced laboratory workflows.
