    Product Basics

    CELLBANKER® 2 is a ready-to-use, serum-free cell cryopreservation medium formulated for a broad spectrum of mammalian cell cultures. The unique formulation enables stable cryopreservation and high viability after the freeze-thaw procedure, without the potential risk of serum contamination.

    For optimum results, cells for cryopreservation should be in log phase of growth. Similar or other standard freezing protocols may be substituted.

    1. Examine and make sure the cell culture is free of contamination, in healthy and at proper confluency.
    2. Perform a cell count to determine the viability of cells.
    3. Centrifuge at 1,000 – 2,000 rpm, 4°C for 3 to 5 minutes to gently pellet the cells. Remove the supernatant with an aspirator.
    4. Gently suspend STEM-CELLBANKER® GMP grade cryopreservation medium (1 mL for 5×10⁵ – 5×10⁶ cells).
    5. Transfer 1 mL of the cell suspension to cryopreservation vial labeled with appropriate information (the cell line name, concentration, passage date etc.).
    6. Place the vials directly in -80℃ for storage.
    7. (OPTIONAL) Transfer the frozen vials to a liquid nitrogen storage tank after the vials have been frozen for at least 24 hours.

    IMPORTANT: Optimum protocol may change with the cell types.

    Procedure for Use


    1. Remove the cryopreservation vial from the freezer and quickly thaw cells in a 37°C shaking water bath or shake by hand.
    2. Transfer the content to a centrifugation tube then immediately dilute and gently mix with 10mL of complete cell culture medium. Using CELLOTION® instead of complete culture medium will prevent adhesion of cells to the wall of the tube, increasing the recovery rate.
    3. Centrifuge cells at 1,000 – 2,000 rpm, 4°C for 3 to 5 minutes. Remove the supernatant with an aspirator.
    4. Gently resuspend the cells with an appropriate volume of complete cell culture medium then plate in a culture flask or plate
    5. Continue the culture procedures according to standard protocols.
