  • Recommended culture vessel coating: Not required
  • Recommended cell culture medium: Mononuclear Cell Maintenance Medium
  • Recommended seeding density: As required (~1 million cells / mL)
  • Recommended centrifugation speed: 400 x g for 10 minutes

Thawing & Plating:

  • Transfer the vial of cells from liquid nitrogen storage with the vial buried in dry ice. Remove the vial from dry ice and transfer it immediately to a 37°C water bath.
  • Thaw the cells quickly in a 37°C water bath until just prior to complete thawing.
  • Wipe the outside of the vial with 70% ethanol.
  • Gently resuspend the cells and transfer to a 15 mL sterile conical tube.
  • Slowly add 10 mL of pre-warmed Mononuclear Cell Maintenance Medium.
  • Rinse the cryovial twice with 1 mL of Mononuclear Cell Maintenance Medium to ensure all of the cells are transferred.
  • Centrifuge the cells at 400 x g for 10 minutes.
  • Carefully remove the supernatant and resuspend the cell pellet in 2 mL of pre-warmed Mononuclear Cell Maintenance Medium.
  • Perform a cell count to determine the number of viable cells
  • Dilute the cells into the required volume of pre-warmed Mononuclear Cell Maintenance Medium.
  • Seed cells into the culture vessel at the required seeding density.
  • Proceed with experiment assays.
  • Incubate the cells at 37°C, 5% CO2 in a humidified incubator.


The PBMCs should be used directly for endpoint assays and should not be cultured long-term or passaged. The Mononuclear Cell Maintenance Medium is designed to maintain PBMCs after thawing and short-term culture. Expansion of PBMCs may lead to a loss of cell types and dominance of certain PBMC subtypes such as T cells. The expanded cells may also exhibit dependency on the particular cytokines and growth factors used.
