20130059381 | SOLUTION FOR NON-PROGRAMMED CELL CRYOPRESERVATION - The invention provides a solution for non-programmed cell cryopreservation, which comprises 1.0-28 w/v % of cell membrane protectant, 1.0-18 w/v % of permeable intracellular protectant, 3.0-28 w/v % of cell sedimentation stabilizer, and the balance of solvent. The cell cryopreservation solution provided by the invention is good for protecting cells. After the cryopreservation solution is added to cells, the cells can be cryopreserved in a refrigerator of −80 DEG C. directly without complicated programmed cryopreservation, thus, the time for cell cryopreservation is shortened greatly and the efficiency of cryopreservation is improved. Therefore, the cryopreservation solution is suitable for cryopreserving a large number of cells. The recovery rate of the cells cryopreserved is high, the growth and differentiation of the recovered cells is normal. The components of the cryopreservation solution are stable, thus the cryopreservation solution can be preserved with good property for a long time. | 03-07-2013 |
20130062569 | PROTEIN-FREE SOLUTION FOR NON-PROGRAMMED CELL CRYOPRESERVATION - The invention provides a protein-free solution for cell cryopreservation, which comprises 1-23 w/v % of cell membrane protectant, 1.0-16 w/v % of permeable intracellular protectant, 3.0-28 w/v % of cell sedimentation stabilizer, and the balance of pH buffer solution. The cell cryopreservation solution of the invention consists of chemical substances only, without any protein content. The components are stable and controllable. The cell cryopreservation solution has long shelf life, high stability between different batches and good protection of cells, and has no effect on the characteristics, normal growth and differentiation of cells; besides, the recovery rate of the cells cryopreserved by the cell cryopreservation solution is high. The cell cryopreservation solution of the invention can be used directly without additional preparation or dilution steps, thus the cryopreservation process is simple, just needing to add cells in the cell cryopreservation solution and putting the solution in an environment of −80 DEG C directly. | 03-14-2013 |
