Directions for use
It is recommended to perform a preliminary experiment without using the Cell Cryopreservation Medium to assess product performance. The product is provided in sterile packaging and should be used under sterile conditions. Suggested Procedure - Cell Cryopreservation
Collect suspension or adherent cells using typical methods. Ensure that the cells are growing well and that the survival rate is > 90% (e.g. cells are in the logarithmic growth phase). Centrifuge at 300 × g for 5 minutes, then discard the supernatant.
Add Cell Cryopreservation Medium until the cell density is within 5 × 105 - 1 × 107 cells/ml. Mix slowly to form a cell suspension.
Transfer the cell suspension to a cyrotube and store in a freezer at -80°C. If storage in liquid nitrogen is required, it is recommended to store overnight at -80°C before transferring the tube into liquid nitrogen. Ensure that the cryotube is completely sealed before storage.
Suggested Procedure - Cell Recovery
Add 5-10 ml of complete medium prewarmed to 37°C into a centrifuge tube.
Remove the cryotube containing the cells from the freezer or liquid nitrogen, and quickly place it in a 37°C water bath. Shake the cryotube gently until it is completely thawed.
Transfer the cell suspension in the cryotube slowly (dropwise) into the medium. Mix gently. Centrifuge at 300 × g for 5 minutes, then discard the supernatant.
Add preheated complete medium. Transfer to a culture vessel by pipetting gently. Incubate at 37°C, 5% CO2.
