KLN205 mouse lung squamous cell carcinoma cell
adherent, epithelial cell-like
No. 359173
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 receiving goods, please contact customer service within 24 hours. if it fails to do so, it will be deemed as good receiving goods. The frozen storage tube shall be stored in a refrigerator at -80 ℃ after receiving the goods. If it is not used for a long time, it shall be transferred to liquid nitrogen storage overnight. T25 form, after receiving the goods, the culture bottle shall be placed in the incubator for rest for 4 hours, and then the cells shall be subjected to routine operation. During recovery, each tube shall not be retained once used up. After recovery, it will be passed on to one generation and can be used normally. Please strictly follow this instruction, otherwise no reissue service will be provided if cell inactivation is caused.
Growth conditions:37 ℃,5% co 2,90% DMEM-H + 10% FBS. DMEM-H:DMEM high sugar culture solution, containing glutamine and sodium pyruvate.
Recovery steps:
(1) 1 new 100mm plate containing 12mL of the above culture solution;
(2) the frozen storage tube is taken out of liquid nitrogen or -80 ℃, bathed in water at 37 ℃ for 1~2min, and moved into the safety cabinet for resuscitation as soon as possible after complete dissolution;
(3) using a sterile straw to suck the dissolved liquid into the new plate and shake well clockwise;
(4) put in (37 ℃,5% CO2) in the incubator, change the liquid overnight and full in 2-4 days.
Subculture/cryopreservation: suck out the old culture solution. after PBS cleaning twice, add 2mL(/100mm dish/T25 bottle) of pancreatin (0.25% Trypsin + 0.02% EDTA) and observe under a microscope. during this period, it is forbidden to shake the culture dish. when the cells just fall off, suck out most of the pancreatin, leave about 0.5mL, move to the incubator for digestion and take out in about 1min. Subculture is terminated by digestion with 6mL of culture solution, and cells are gently blown evenly, and then subculture can be 1:3. For cryopreservation, 3mL of cryopreservation solution (50% basic medium + 40% FBS + 10% DMSO) is used to terminate digestion, blow evenly, divide into 3 frozen storage tubes, freeze storage at -80 ℃ with a program cooling box, and transfer to liquid nitrogen for storage overnight.
Recovery record: According to the recovery instructions, the results of the cell recovery are reported as follows:
