Mouse T lymphoma cells (chicken OVA gene modification)

Culture medium	RPMI-1640 complete medium (RPMI-1640 complete medium):90% RPMI-1640 + 10% FBS
Subculture procedure	Recovery steps: ① Take out the frozen vial from liquid nitrogen or -80 ℃ and put it into PE gloves, quickly subtract into a water bath pot at 37 ℃, shake the frozen vial to accelerate dissolution, and completely dissolve within 1 minute. (2) Add the dissolved cell liquid into a centrifuge tube containing 9ml of complete culture medium in an ultra-clean table, centrifuge at 1000-1200rpm/min for 5 minutes, discard the supernatant, resuspend the cells with 1-2ml of complete media. ③The cell suspension was then added to a T25 flask containing 6-8mL complete medium and placed in an incubator for upright cultivation. Cell subculturing: ① Centrifugation: collect cells, centrifuge at 1000rpm for 5 minutes, discard the supernatant, add 1-2mL of culture solution and blow well, and dispense the cell suspension into a fresh T25 flask containing 8ml of culture medium according to a ratio of 1:2. (2) Half-volume liquid medium exchange: after the culture flask is allowed to stand for 5-10 minutes, half of the supernatant medium is gently sucked away, the remaining medium with cell precipitation is resuspended and mixed evenly, and the cell suspension is divided into a fresh T25 flask containing 8ml of medium according to a ratio of 1:2. (3) Pay attention to the change of pH of medium and cell density, renew the medium regularly (2-3 times a week), and repeat the subculture or cryopreservation when the cell density reaches more than 2 × 106 cells/ml.

Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the cells are well. For the frozen cells, it shall be stored in the refrigerator at -80 ℃ upon arrival. If they are not used for a long time, they shall be transferred to liquid nitrogen for storage overnight. Recovered cells in T25 culture flask, upon receipt, put the culture flask in the incubator for 4h, and then carry out handling procedure. During recovery, each vial shall be used up once and shall not be retained. After recovery, the cells can be passed on to the next generation and can be used normally. Please operate in strict accordance with this instruction, otherwise the replacement of cells are not be available in case of loss of cell viability.

culture conditions: 37 ℃,5% CO₂,CM2-1 culture solution. CM2-1 culture solution: 90% RPMI-1640 + 10% FBS. RPMI-1640:1640 culture solution, containing glutamine.

Recovery steps:
(1)prepare a new 100mm culture dish containing 12ml of the above culture medium;
(2)remove the frozen vial from liquid nitrogen or refrigerator at -80℃, thaw the vial in 37°C water bath for 1-2 minutes. Transfer the vial to biosafety cabinet for culture as soon as the contents are completely thawed.
(3)draw the solution with a sterile pipette, drip into a new culture dish, and mix it evenly by shaking clockwise;
(4) Put it into incubator (37℃，5%CO2）, change the media overnight, and it will grow up in 4-6 days.

Passage / cryopreservation:

(1)Passage: terminate aspirate and dispense into 3~6 culture dishes.; gently shake well and put them into incubator for culture.

(2) Cryopreservation: (110g, 3min) centrifuge after that terminate digestion with 3ml of cryopreservation solution （90%FBS+10%DMSO), aspirate and dispense into 3 frozen vials, and cryopreserve at -80 ℃ with a programmed cooling box.

Recovery record: According to the recovery instructions, the results of the cell recovery are reported as follows:

item	quality standard	recovery record
viability:	suspension growth rate ≥ 80.0% in 96 hours	inoculation with 20% cell solution, suspension growth rate reaches 40.0% in 18 hours, and 80.0% in 72 hours
cell morphology:	suspension, lymphoblast-like	CM2-1 culture medium, suspended, lymphoblast-like, round
attached:
conclusion:	good viability, no abnormal cell morphology, qualified
