Gibco® Recovery™ Cell Culture Freezing Medium is a complete, ready-to-use freezing medium for cryopreservation of a wide variety of mammalian cells including CHO-S, CHO-K1, HEK 293, Jurkat, and NIH 3T3. Gibco® Recovery™ Cell Culture Freezing Medium features:
• Classic formulation optimized for better performance
• Suitability for a wide variety of mammalian cells
• Quality and performance testing

Classic formulation optimized for better performance
For many years, researchers have used a common recipe for making freezing medium: High-glucose Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% serum and 10% DMSO. Gibco® Recovery™ Cell Culture Freezing Medium is an optimized version of this classic formulation, using high-quality Gibco® Bovine Serum and Gibco® Fetal Bovine Serum to provide improved cell recovery and viability after thawing.

Suitability for a wide variety of mammalian cells
Gibco® Recovery™ Cell Culture Freezing Medium can be used to freeze most mammalian cells cultured in DMEM, DMEM/F-12, MEM, RPMI 1640 and Ham's F-12, including CHO-S, CHO-K1, HEK 293, Jurkat, and NIH 3T3 cells.

Quality and performance testing
Gibco® Recovery™ Cell Culture Freezing Medium is quality tested for pH, osmolality, sterility and endotoxin. In addition, each lot of Gibco® Recovery™ Cell Culture Freezing Medium is performance tested using CHO-K1 cells.
