Abstract
Lewis lab protocol for culturing RAW264.7 cells.
Materials
- DMEM (31966047, Gibco)
- 10 % heat-inactivated FCS
Troubleshooting
Subculturing
Remove the medium and add 5 ml of fresh medium to 75 cm^2 flask.
Scrap cells with a cell scraper.
Aliquot cell suspension into new flask at a ratio of 1:5 to 1:10.
Incubate the culture at 37°C, 5% CO2 in a suitable incubator.
Subculture every 2 to 3 days.
Thawing
Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water. Thawing should be rapid (approximately 2 minutes).
Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol.
Centrifuge the cell suspension at approximately 300 x g for 5 minutes. Discard the supernatant and resuspend the cell pellet in an appropriate amount of fresh growth medium and transfer the cells to an appropriate size vessel.
Incubate the culture at 37°C, 5% CO2 in a suitable incubator.
Freezing
Freeze cell suspension in complete growth medium supplemented with 10 % (v/v) DMSO at 1 to 5 x 10^6 cells/ml.
