flow cytometry calibrator |
| Regulation Description |
Automated differential cell counter. |
| Definition |
Flow cytometer calibrators are polystyrene or other particles whose defined characteristics (e.g. number, size, scatter or fluorescence intensity) is used to standardize instrumentation or to quantify other particles or analytes measured by flow cytometers. |
| Physical State |
Beads for performing absolute counts of cells in suspension by flow cytometry Beads for standardizing flow cytometers Beads that are used to calibrate fluorescence intensity to quantify ligand binding or fluorogenic assays performed by flow cytometry Beads that are used to perform calibration in addition to quality control of flow cytometric assays. SHOULD NOT INCLUDE beads that are only used for quality control |
| Technical Method |
Bead associated fluorescence or scattered light is used to determine the number of other particles in solution ratio-metrically and to calibrate fluorescence intensity scales on a flow cytometer to standardize measures. |
