Protect your sensitive cell lines with CELLBANKER Cell Freezing Media, a trusted solution for stable long-term storage of any cell type.
Materials for freezing cells We suggest using the following materials for the cell freezing protocol: Log-phase cultured cells Complete growth medium:basal medium,serum, andsupplementspre-warmed to 37°C Cryoprotective agent such asDMSO(use a bottle set aside for cell culture; open only in...
Resuspend the cell pellet in cold freezing medium at the recommended viable cell density for the specific cell type. 按照特定细胞类型的建议活细胞密度,将细胞颗粒悬浮在冷冻培养基中 Dispense aliquots of the cell suspension into cryogenic storage vials. As you aliquot them, frequently and gently mix th...
Cell recovery of replicate cultures from different cryopreservation media were normalized to Recovery Cell Culture Freezing Medium and plotted (average normalized recovery±standard error). Result: For cryopreservation of both adherent and suspension cell lines, Recovery freezing medium results in an ...
2. For suspension cells proceed to step 3. For adherent cells, gently detach cells from the substrate on which they are growing using a suitable dissociation reagent such as TrypLETM. Resuspend cells in complete medium required for that cell type. 3. Transfer cell suspension to a sterile 15-...
The freezing of biological cell suspensions can be understood in terms of ice formation in the external suspension medium and the cellular reactions to the changing environment. Cryomicroscopy allows a quantitative analysis of both categories of phenomena. Besides freezing stages of appropriate thermal ...

Spin the cell suspension gently at 300g for 5 min. Carefully remove the medium without disturbing the pellet. Gently resuspend the cells in 10ml of fresh appropriate culture medium and place in a small T25 flask (Corning 3056). Take 1ml from this flask and add to 9mls of complete cultu...
