Subculture procedure	Resuscitation steps: ① Remove the frozen vial from liquid nitrogen or -80 ℃ refrigerator and place it in PE gloves. Quickly immerse it in a 37 ℃ water bath, shake the vial to accelerate dissolution, and dissolve it completely within 1 minute; ② Add the dissolved cell solution into a centrifuge tube containing 9mL of complete medium on a ultra-clean bench, centrifuge at 1000-1200rpm for 3-5 minutes, discard the supernatant, and resuspend the cells in 1-2mL of complete medium. ③ Add the cell suspension into a T25 flask containing 6-7mL of complete medium and place the flask vertically in an incubator. Cell passage: ① Centrifuge method: Collect cells, centrifuge at 1000rpm for 5 minutes, discard the supernatant, add 1-2mL of culture medium and blow evenly. Divide the cell suspension into fresh T25 flasks containing 8mL of culture medium at a ratio of 1:2.② Half volume liquid exchange method: Please gently aspirate half of the supernatant culture medium, resuspend the remaining culture medium with cell sediment, and divide the cell suspension into fresh T25 flask containing 8mL of culture medium in a ratio of 1:2.③ Pay attention to changes in the pH value of the culture medium and cell density, change the medium regularly (2-3 times a week), and repeat the passage operation or cryopreservation when the cell density reaches greater than 2 × 10^6 cells/mL.

Receiving notice:

1 Upon arrival, it is suggested to sit the cells in a incubator for about 4 hours, and then renew the media for recovery or subculture according to the cell density.

2 Collect the cells by centrifuge, re-suspend the collected cells with 10ml of complete media, transfer to fresh culture flask/vessel and cultivate overnight, and dispense into separate vials for subculture according to the cell density.

3 Clustered growth: agitate the culture flask to disperse the clustered cells and continue to recover or subculture.

Recovery and subculture procedure of cells ( under strict aseptic conditions )

1 The suspension cells is normally handled by changing half of the solution and sub-cultured in separate flasks, that is, transfer half of the suspension liquid to a fresh flask/vessel, add appropriate complete medium and culture it in the incubator; It can also be sub-cultured in separate flasks according to cell density.

2 Pay attention to the change of pH value of medium and cell density, renew the medium regularly, and repeat the subculture or cryopreservation when the cell density reaches 70%-80%.

Special attention: (if handle in public laboratory or first time to culture the cells, it is recommended to add penicillin streptomycin into the media)

1 Upon the receipt of the cells, renew the solution with fresh 10% FBS medium as soon as possible. It is not recommended to use the medium used for transportation in the original flask.

2 Please take photos and contact the technicians in time if the culture flask leaks upon the receipt of cells.

3 Any compliant on the cells, please take photos and contctat our technicians.
