Wellington, Auckland, New Zealand bdbiosciences. NOTE Invert bead vials completely when adding a drop to the tube. All forms are provided in stabilized, buffered saline with 0.
Optimize instrument settings following two-color setup using a blood sample stained with any combination of monoclonal antibodies that identifies separate non-overlapping cell populations, such as FITClabeled and PE-labeled monoclonal antibodies. Figure 1 through Figure 4 show examples of optimization for two- three- and four-color applications.
Because BD Calibrite beads calibritf 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 calibgite the flow cytometer.
BD Calibrite™ – BD Calibrite PerCP-Cy Beads – BD Biosciences
The FSC threshold is adjusted to a level that minimizes background signal if any. Refer to the information appropriate to the instrument setup you are performing.
How to make the beaded number line. Gently mix the BD Calibrite bead vials, then add 1 drop of beads to capibrite tube as indicated in the table below. Always refer to the appropriate application note or reagent Calibeite. Preparation of Test Suspensions Prepare all bead suspensions immediately prior to use.
BD Calibrite™ Beads
BD Calibrite calibrjte are used to determine the appropriate compensation settings. Both scatter and fluorescent light signals are detected. Record PMT voltages and channel separations obtained for each parameter in a daily log sheet.
Make sure to obtain a full drop of beads. NOTE Over a period of time, the fluorescence separation might decrease. Daily use is recommended for monitoring instrument performance over time. In some cases the software may not be able to automatically set up the instrument. Label two 12 x mm polystyrene tubes Tube A and Tube B. Do not use after the expiration date shown on the label.
BD Calibrite™ Beads
Beads used beyond their stability begin to show a decrease in separation between unlabeled and labeled populations, resulting in Sensitivity Test bsads.
It is not licensed for any other use. FL1, FL2, and FL3 fluorescence sensitivity is determined by measuring the mean channel separation between the signal of the labeled beads and the unlabeled beads.
Compensation adjustments for FL1, FL2, and FL3 correct for spectral overlap by shifting the labeled bead populations so they are aligned with the corresponding unlabeled bead populations.
Following PMT and compensation adjustment, the software performs a Sensitivity Test using the appropriate mixed-bead suspension. A thorough investigation of sucrose Concentration values are listed in the following table: For information on use, refer to the appropriate instrument manual. Beads used beyond their stability begin to show a decrease in separation between unlabeled and labeled populations, possibly resulting in Sensitivity Test failure.
The channel separation and PMT voltages for each of the four parameters should be maintained in a daily log to track instrument performance.
See Optimization and Quality Control on page 4. Instrument settings might need to be manually optimized before running cells. A minimum channel separation must be met for the scatter and fluorescence parameters. Optimizing Scatter Figure 1 shows a lysed whole blood LWB sample from a normal donor before and after optimization.
BD Calibrite PerCP-Cy5.5 Beads
Weather and Climate for Beadw. Optimization following three- and four-color setup can vary depending on the application. Notice populations with a lower FSC signal than lymphocytes debris, for example can be excluded by increasing the FSC threshold level. The drop should be cloudy, indicating the beads are properly mixed.
Corrective action might be required if the average separation varies by more than 2. Cqlibrite product is licensed for sale only for in vitro diagnostics. An APC-labeled bead is available separately and may be used with the 3-color kit to perform four-color setup. Perform a Sensitivity Test using Tube B.
