Overview

CFSE is used to fluorescently label live cells in order to track them. 5,6-CFDA/SE is membrane permeable, but trapped in the cell when converted by intracellular esterases. CFSE is equally partitioned to daughter cells during division and can be used to measure cell proliferation.

Materials

  • 15 mL polypropylene tubes
  • PBS
  • 5,6-CFDA/SE Invitrogen C1157 dissolved in DMSO at 5 mM and stored at -20°C.

Procedure

  1. Suspend PBMCs at 10x106 cells/mL in PBS alone.
  2. Cells should be in PBS for CFSE labeling.
  3. If CFSE negative control is needed, remove cells now.
  4. Make '2X' concentration (10 μM) in PBS
    • For example: add 5 mL PBS + 10 μL 5 mM CFSE
  5. Combine 1:1 PBMC cells + CFSE (e.g. 5 mL PBMCs + 5 mL CFSE) in 15mL tube.
  6. Place in 37°C H2O bath x 10 min.
  7. Wash in 10 mL complete medium.
  8. Resuspend in medium at desired density
