Human small cell lung cancer cells

Culture medium	SHP-77 Special Medium: 88% RPMI-1640 + 10% FBS + 1% L-Glutamine + 1% Sodium Pyruvate
Subculture procedure	Recovery steps: ① Take out the frozen vial from liquid nitrogen or -80 ℃ refrigerator and put it into PE gloves, quickly submerse into a 37 ℃ water bath, shake 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 3-5min, discard the supernatant, resuspend the cells with 1-2ml of complete media. ③The cell suspension was then added to the T25 flask containing 6-7mL of complete medium and placed in an incubator for culture. The culture flask is recommended to be cultured uprightly. cell subculture: ① centrifugation: collect cells, centrifuge at 1000rpm for 5min, 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 medium exchange method: half-volume medium exchange method can be selected; Please gently suck half of the supernatant culture medium, resuspend and mix the remaining culture medium with cell precipitation, and divide the cell suspension into a fresh T25 flask containing 8mL culture 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.
Growth conditions	37 ℃;5% CO2 + 95% air;
Growth characteristics	Suspension growth
Storage conditions	Liquid nitrogen
Type	Epithelial cell
Safety level	1
morphology	Epithelial cell-like, round, multiple clusters, clean background

application	SHP-77 can be used as an in vitro target in 51Cr and 111In release cytotoxicity tests and in vivo nude mice tests to evaluate the immunoreactivity of cells and serum of lung cancer patients. These cells can be used to assess the immune status of SCLC patients receiving radiotherapy or chemotherapy.

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 If the adherent cells are received in the form of ( partial) suspension, please centrifuge the suspended cells in time, add 15% serum complete medium to a fresh culture dish / vial and continue to culture for 3 days; At the same time, the remaining adherent cells in the original culture flask were renewed with 15% serum complete medium and cultured for 2-3 days. If the cells do not proliferate after 3 days but continue to detach and die, please contact the technicians.
3 Slow growth of adherent cells: properly increase the serum concentration (no more than 20%) or transfer to a fresh culture flask for further culture after trypsin digestion according to the cell density.
4 Uneven growth: if adherent cells grow unevenly and is island-like, they can be digested, dispersed, and cultured with fresh medium.

Recovery and subculture procedure ( under strict aseptic conditions )

1 Remove the medium in the original culture flask, rinse twice with PBS, and add 1~2 ml of 0.25% EDTA for trypsin digestion (usually in 1~2min)
2 Observe the digestion under the microscope. When the cell edge shrinks and adherent is loose (but not floating), remove the trypsin, add 6~8ml complete medium, aspirate the cell layer off.
3 Transfer part of the cell suspension to a fresh culture vessel / flask, add appropriate complete medium, and culture it in the incubator.
4 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 bottle.
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.
