Comparative video of preservation efficiency of mouse fibroblast cell line

Bambanker®

Bambanker®

Self-prepared preservative solution
(FBS containing 10% DMSO)
Self-prepared preservative solution

Experimental conditions
• Cells used:
Mouse fibroblast cell lines (MEF obtained from American Type Culture Collection)
• Number of cells stored:
4×106 cells/vial. Each cell was suspended in 1 ml of preservative solution.
• Storage temperature:
-80ºC. Cells were directly placed in a storage box and cooled without using BICELL, etc.
• Storage period: 45 days

A number of dead cells as well as stagnation of growth potential were observed in self-prepared preservative solution; however, Bambanker® showed vigorous cell proliferation ability immediately after thawing, and survival of almost all cells was confirmed. (For details, refer to the user’s report at the top of the page)

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>

Features

  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.
