Serum-Free Cell Freezing Medium
The Serum-Free Cell Freezing Medium is a ready-to-use, animal component-free, serum-free, and protein-free cryopreservation solution optimised for various cell lines. When culturing cells in a serum-free environment, it is vital to also maintain serum-free conditions during cryopreservation.
The Serum-Free Cell Freezing Medium has been shown to result in high rates of cell viability, proliferation, adherence (in appropriate lines), and bioactivity/ expression following freezing and thawing. Superior results were observed when comparing both serum-containing freezing media as well as competing serum-free products. This freezing medium is therefore an ideal product for both serum-containing and serum-free applications.
The Serum-Free Cell Freezing Medium has been extensively tested on multiple cell lines, including 3T3, BGM, vero cells, MRC-5, HEK-293, HEp-2, BSC-1, BF16-F10, BHK-21, CHO, HELA, MA-10, and mesenchymal cells.

- Suitable for use in cell banks and biopharmaceutical applications
Instructions For Use
Cryopreservation of serum-free cell cultures
- For freezing adherent cells, detach cells using the appropriate dissociation solution. (For freezing of cells in suspention, skip to step 2.)
- Centrifuge to pellet the cells at 200 – 300 x g for 3 to 5 minutes.
- Suspend the cell pellet in cold Serum-Free Cell Freezing Medium at a concentration of 3 to 5 million cells/mL.
- Freeze the cells gradually (1 to 2°C per minute) and store them in liquid nitrogen.
- Viability and recovery of cryopreserved cells should be evaluated 24 hours after storage of vials in liquid nitrogen by following the thawing procedure outlined below.
Thawing cryopreserved cells
- Thawing should be performed at 37°C.
- Immediately after thawing, suspend the cells in serum-free growth medium at a ratio of at least 1:10.
- Centrifuge and suspend in growth medium as desired.
- Culture the cells according to the recommended seeding density.
