Cryopan II
Chemically Defined, Protein-Free Cell Freezing Medium with 10 % DMSO
Chemically defined, protein-free freezing medium with 10 % DMSO for cryopreservation of cells
RUO (P07-93100) · GMP catalogue product (CT-94100)
Cryopan II is a chemically defined, serum-free and protein-free freezing medium with 10 % DMSO for the cryopreservation of a broad range of cell types – both primary and established, in adherent and suspension culture. Its chemically defined composition, an optimized mixture of salts, sugar, 10 % DMSO and additional antifreeze substances free from animal- and human-derived components, ensures reproducible preservation and is particularly well suited to serum-free cultured cells. High post-thaw viability has been demonstrated across a broad cell panel, including hybridoma, Jurkat, HEK293S, CHO-K1, L929, human MSC, HUVEC and Vero cells.
Chemically defined, protein-free cryopreservation – also available in GMP grade. Cryopan II preserves serum-free cultured cells with a defined, animal- and human-component-free formulation for high viability after thawing; the matched GMP grade CT-94100, manufactured GMP-compliant by PAN-Celltech, extends Cryopan II from research into cell banking, antibody manufacturing and cell & gene therapy.

Frequently asked questions
Is Cryopan II serum-free and protein-free?
Yes. Cryopan II is a chemically defined, serum-free and protein-free freezing medium, free of animal- and human-derived components.
What does it contain?
An optimized, chemically defined mixture of salts, sugar, 10 % DMSO and additional antifreeze substances; it contains no animal or human components.
Which cells is it suitable for?
Human and animal cell lines and primary cells, in both adherent and suspension culture. High post-thaw viability has been shown for hybridoma, Jurkat, HEK293S, CHO-K1, L929, human MSC, HUVEC and Vero cells.
How should cells be frozen?
Use viable cells in the logarithmic growth phase at 5×10^5 – 2×10^6 cells/ml in cold Cryopan II, 0.5-1.5 ml per cryotube, freezing at a controlled rate of approximately 1 °C per minute before transfer to the liquid-nitrogen vapor phase.
How are cells thawed?
Thaw the cryotubes promptly in warm water (no more than 2 minutes), add growth medium dropwise, centrifuge and resuspend in the designated culture medium.
Is a GMP grade available?
A matched GMP grade (CT-94100), manufactured GMP-compliant by PAN-Celltech, is available. Contact us to discuss GMP supply.
