Human gastric cancer cells
Culture medium RPMI-1640 complete medium: 90% RPMI-1640 + 10% FBS
Subculture procedure Recovery steps: ① The frozen vial is taken out of liquid nitrogen or -80 ℃ refrigerator and put into PE gloves, quickly submersed into a 37 ℃ water bath pan, shaken The frozen vial to accelerate dissolution, and it is advisable to dissolve all within 1min; (2) Add the dissolved cell solution into a centrifuge tube containing 9ml of complete culture medium in an ultra-clean table, centrifuge at 1000-1200rpm for 5min, discard the supernatant, resuspend the cells with 1-2ml of complete media. ③The cell suspension was then added to the T25 flask containing 6-8mL of complete medium and placed in an incubator for culture.
cell subculture: ① transfer the cell suspension solution into a centrifuge tube, centrifuge at 1000rpm for 5min, and collect cells; (2) rinse T25 flask twice with PBS, add 1-2mL pancreatin (0.25% Trypsin + 0.02% EDTA); 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, , the cell layer can be seen to detach with the naked eye, that is, digestion is completed, otherwise digestion continues), directly suck out pancreatin, add 5-6mL of complete medium, gently blow the cell layer off. (3) The cells obtained from the above two steps are evenly mixed and then dispensed into fresh T25 flasks as a ratio of 1:2. add appropriate complete medium, mix the cell suspension evenly, and culture in an incubator. ④ 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 80%-90%.

MKN-45 human gastric cancer cells

semi-adherent and semi-suspended, epithelial cell-like

No. 337681

Culture:37 ℃,5% CO2 CM2-1 culture solution

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

Biosafety level: 1 , handle in ultra-clean 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% CO2,CM2-1 culture solution. CM2-1 culture solution: 90% RPMI-1640 + 10% FBS. RPMI-1640:1640 medium, containing glutamine.

Recovery steps:
(1)  Prepare a fresh 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 2-4 days.

Subculture/ cryopreservation:  centrifuge the suspended cells at 110g for 3 minutes to collect the cells, rinse twice with PBS, add 2ml of 0.25%Trypsin+0.02%EDTA. Observe under the microscope, remove most of the trypsin(with 0.5ml left) when the cells detach. transfer it to the incubator for digestion about 2 minutes, and take it out.

(1)  Subculture: terminate digestion of cells in culture dish with 10ml of CM2-1 culture media, re-suspend the cells in centrifuge tube with 2ml of CM2-1 culture media, mix the 12ml of the solution evenly and dispense into 3~6 culture dishes.

(2) Cryopreservation: terminate digestion with 3ml of cryopreservation solution (90%FBS+10%DMSO), aspirate and mix evenly with the cells in centrifuge tube, 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: adherence is observed in 18 hours,  the cell adherence rate ≥ 80.0% in 90hours adherence is observed in 12hours,  the cell adherence rate ≥ 80.0% in 90hours
cell morphology: semi-adherent and semi-suspended, epithelial cell-like in CM2-1 culture medium, semi-adherent and semi-suspended, epithelial cell-like, polygonal, round
attached figure:
Conclusion: good viability, no abnormal cell morphology, qualified
