BAMBANKER® is a serum-free medium for long-term freezing at -80℃ and preservation of valuable culture cells such as tumor and normal cells.

<For Research Use Only>


  1. Serum-free
  2. Ready-to-use medium for preservation of cells
  3. No program freezer is required
  4. Rapid and long-term freezing and preservation in a deep freezer
  5. zUsable for 2years at 2~4℃

Operating Procedure

  1. Centrifuge the cells in logarithmic growth phase and collect 5×105 ~ 1×107cells.
  2. Suspend the collected cells in 1mL of this medium and place the cells in cryotubes for freezing and preservation.
    Then freeze and preserve the cells at -80℃ without preliminary freezing. The cells frozen at -80℃ can be preserved subsequently in liquid nitrogen.
  3. Thawing must be carried out quickly in a constant-temperature chamber or bath.

★ The cells must be frozen in logarithmic growth phase.
