CTS™ (Cell Therapy Systems) Synth-a-Freeze® medium is a chemically defined, protein-free liquid cryopreservation medium intended for freezing and storing a variety of mammalian cell types including stem cells. Synth-a-Freeze® CTS™ media is optimally formulated without antibiotics, antimycotics, hormones, growth factors, serum, or protein and buffered with HEPES and sodium bicarbonate.

Use for cryopreserving a variety of primary and stem cells

• Save time and effort with 4 degree stable storage of thawed media and compatibility with a variety freezing protocols
• Be ready for clinical research with this cGmP manufactured, chemically defined, protein-free formula

Cryopreserve a Variety of Cell Types
Cell Therapy Systems Synth-a-Freeze® CTS™ media performs comparable to our standard, serum-containing cryopreservation medium for cryopreserving a variety of cell types including human Embryonic Stem Cells, Neural Stem Cells (Ref 1), Mesenchymal Stem Cells and Keratinocytes (Ref 2). We do not recommend using Synth-a-Freeze® media for cryopreservation of human epidermal melanocytes.

Simple Incorporation into Your Current Freezing Protocol
Synth-a-Freeze® CTS™ media can be used with any standard freezing protocol. Just add thawed Cell Therapy Systems Synth-a-Freeze® CTS™ media to detached and pelleted cells, aliquot, and freeze. For optimal results, the use of a controlled-rate freezer is recommended.
