Serum-Free Cell Freezing Medium


BAMBANKER™ is a serum-free medium for long-term freezing at -80°C and preservation of valuable culture cells such as tumor cells and normal cells.
BAMBANKER™ Direct is improved operability. It doesn't require centrifugation for cell collecting.

Comparison of preservation efficiency of mouse fibroblast strain

BAMBANKER™ Self prepared solution
Cells used: Mouse fibroblast cell line
Number of cells stored: 4 × 106 cells / vial. Each cell was suspended in 1mL of preservation solution.
Storage temperature: -80°C. Cells were directly placed in storage box and cooled without using BICELL, etc.
Storage period: 45 days
Thawing method: Cells were thawed according to the conventional method.
Method of measuring
preservatiion efficiency:
After thawing, 5 x 104 cells were inoculated into a 24-well culture plate with 1 mL DMEM medium, and the cell density per culturing area was measured by successive timlapse imaging.
Data by Shota Moriya, Department of Biochemistry, Tokyo Medical University

Better cell viability was obtained using BAMBANKER™ than self-prepared preservative solution.
