Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Remove medium, add fresh 0.25% trypsin to 0.02% EDTA, let sit for 2 to 3 minutes, remove trypsin solution and let the culture sit at room temperature for 5 to 10 minutes or until the cells detach. Add fresh medium, aspirate and dispense into new flasks. ALTERNATIVELY, cultures also can be maintained by addition or replacement of fresh medium. Start cultures at 2 x 104 cells/mL and maintain between 2 x 104 and 1 x 106 cells/mL.
Subcultivation Ratio: 1:4 to 1:8
Growth Properties: Monolayer or suspension
Medium Renewal: Two to three times weekly
Complete growth medium described above supplemented with 5% (v/v) DMSO. Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
