The manufacturer recommends storing the cells in IC Fixation Buffer at a ratio of 1/1 with the cell suspension. Note 2: For compensation of fluorophore-labeled Abs for surface staining, intracellular staining, and viability staining, we recommend utilizing the supplied UltraComp beads. For compensation with the fluorophore-labeled probes, the manufacturer recommends employing the Compensation Kit together with the UltraComp beads. It is not recommended replacing the Compensation Kit with other fluorophore-labeled Abs that are detected inside the very same BP filters. Alternatively, samples is often single-stained with house-keeping gene probes labeled in all four forms and utilised as constructive controls for compensation.12.4 Materials: The PrimeFlowTM RNA Assay kit (ThermoFisher, 888005-210) includes the following material: PrimeFlowTM RNA Fixation Buffer 1A (008100), PrimeFlowTM RNA Fixation Buffer 1B (008200), PrimeFlowTM RNA Permeabilization Buffer (10 (008300), PrimeFlowTM RNA Fixation Buffer two (eight (008400), PrimeFlowTM RNA Wash Buffer (009180), PrimeFlowTM RNA Target Probe Diluent (0018185), PrimeFlowTM RNA PreAmp Mix (006000), PrimeFlowTM RNA Amp Mix (0016001), PrimeFlowTM RNA Label Probe Diluent (009183).
