Preparing the CS&T Beads
The BD™ Cytometer Setup and Tracking beads consist of bright, mid, and dim
beads dyed with a mixture of fluorochromes. Use the beads to define a baseline
and to check cytometer performance using the CS&T application.
See the BD
Cytometer Setup and Tracking beads package insert for more
instructions about preparing the bead suspension.
1 Mix the beads by gently inverting the vial.
2 In a 12 x 75-mm tube, add 0.35 mL of sheath fluid and 1 drop of beads.
NOTE Beads are stable at 2°C to 25°C for no more than 20 minutes if
stored in direct light, and up to 8 hours if protected from light.
