The suspensions are stable for a longer period of time in Bead Dilution Buffer. BD Calibrite beads are used to determine the appropriate compensation settings. See Figure 1 through Figure 5 for examples. Instrument settings might need to be manually optimized before running cells. UV Bead lab with graph. Following PMT and compensation adjustment, the software performs a Sensitivity Test using the appropriate mixed-bead suspension.
NOTE Different immunophenotyping preparation methods might require different optimization procedures. The beads are used to adjust instrument settings, set fluorescence compensation, and check instrument sensitivity. Make sure to obtain a full drop of beads. Gently mix the BD Calibrite bead vials, then add caljbrite drop of beads to each tube as indicated in the table below.
For information on use, refer to the appropriate instrument manual. Compensation adjustments for FL1, FL2, and FL3 correct for spectral overlap by geads the labeled bead populations so they are aligned with the corresponding unlabeled bead calibrihe. Beads used beyond their stability begin to show a decrease in separation between unlabeled and labeled populations, resulting in Sensitivity Test failure. Optimize settings for your sample, as needed.
Adjustment is similar for PerCP-Cy5. Optimizing Scatter Figure 1 shows a lysed whole blood LWB sample from a normal donor before and after optimization.

Record PMT voltages and channel separations obtained for each parameter in a daily log sheet. Always refer to the appropriate application note or reagent IFU.
FL1, FL2, and FL3 fluorescence sensitivity is determined by calibriet the mean channel separation between the signal of the labeled beads and the unlabeled beads. Prepare a blood sample daily from a normal donor. See Optimization and Quality Control on page 4.
Mix bead vials by gentle inversion or very gentle vortexing prior to use. Daily use is recommended for monitoring instrument performance over time. For further assistance, contact your BD Biosciences service calibrife.
Forward scatter FSC and side scatter SSC instrument sensitivity are measured by the mean channel separation between the light-scatter signal of the beads and background signal electronic and optical.
Because BD Calibrite beads simulate unstained cells and cells that have been stained labeled with fluorochrome-conjugated antibodies, the beads are used to adjust the instrument settings before cell samples are run on the flow cytometer. If deterioration is suspected, prepare a new bead suspension and check instrument conditions. Corrective action might be required if the average separation brads by more than 2.
BD Calibrite™ Beads
Reagents are sufficient to perform 25 tests. The FSC threshold is adjusted to a level that minimizes background signal if any.
Label two bedas x mm polystyrene tubes Tube A and Tube B. In some cases the software may not be able to automatically set up the instrument. Figure 1 through Figure 4 show examples of optimization for two- three- and four-color applications.
If this occurs, manually adjust the settings.
Use the same staining method and run in parallel with the test samples. Generate a printout of the Sensitivity Test results and keep the printouts in a log book. Perform a Sensitivity Test using Tube B. A minimum channel separation must be met for the scatter and fluorescence parameters. BD Calibrite beads are for in vitro diagnostic use.
See examples in Optimization and Quality Control on page 4. A thorough investigation of sucrose Concentration values are listed in the following table: Notice populations with a lower FSC signal than lymphocytes debris, for example can be excluded by increasing the FSC threshold level.
Wellington, Auckland, New Zealand bdbiosciences. The decrease in separation for a wide variety of bead lots has been within 2. The 2color kit contains three different types of BD Calibrite beads: It might be necessary to adjust the FSC and SSC amplifiers so that all leucocyte populations cakibrite on scale, and beadd adjust compensation and threshold settings see Figure 1.
