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 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 5-6mL of complete medium and place the flask in an incubator. Cell passage: ① Remove the medium, rinse twice with PBS , and add 1-2mL pancreatin (0.25% Trypsin + 0.02% EDTA); ② Observe the digestion situation under the microscope. When the cell edge shrinks and the adherent is loose (a pasteur pipette can be used to suck up some pancreatin and gently blow somewhere in the cell layer, and the cell layer can be seen to detach with naked eyes, I .e. digestion is completed, otherwise digestion is continued), directly suck out pancreatin, add 5-6mL of complete medium, gently blow the cell layer off. ③ Divide the cell suspension into a fresh T25 flask at a ratio of 1:2, add appropriate complete culture medium, mix the cell suspension evenly, and culture it in the incubator.; ④ 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 80% -90%.

NCI-H2009 human lung adenocarcinoma cells

adherent, epithelial cell-like

No. 358037

Product format: 2ml frozen vial x 2, or T25 flask x 1

Biosafety level: 1, handle in ultra-clear table or safety cabinet

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.

Growth conditions:37 ℃,5% co ₂,90% EMEM + 10% FBS. EMEM:MEM/EBSS culture medium, 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.

Subculture/cryopreservation: remove the medium, rinse twice with PBS , and add 1-2mL pancreatin (0.25% Trypsin + 0.02% EDTA); observe under a microscope, do not shake the culture dish during this period, when the cells detach, suck out most of the pancreatin with about 0.5ml remained, move to the incubator for digestion, and take out in about 3min. For subculture, digestion is terminated by 6mL of culture solution, and subculture at 1:2. For cryopreservation, terminate the digestion with 3mL of cryopreservation solution ( 50% base medium+40%FBS+10%DMSO ), blow evenly, dispense into 3 frozen vials, and freeze at -80 ℃ with a program 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:	adherence is observed in 18 hours, the cell adherence rate ≥ 80.0% in 108 hours	adherence is observed in 18 hours, cell adherence rate ≥ 80.0% in 96 hours
cell morphology:	Adherence, epithelial cell-like	Adherent, epithelial-like, polygonal
attached：
Conclusion:	good viability, and no abnormal cell morphology, qualified
