To make mL DMEM
start with mL water
add: g DMEM*
add: g NaHCO3
add: g HEPES, then pH to 7.2 (initial pH = ~7.1)
add: mL FBS
add: mL anti/anti

bring to final volume, filter sterilize in BSC, refrigerate

  • if using DMEM without pyruvate, add 1 mL Na Pyruvate (100mM) per 100 mL medium

Mix DMEM, NaHCO3, HEPES in about 70% of the final volume of dH2O.
Initial pH ~7.5
Adjust pH to 7.2 with HCl (it will rise to 7.3 in the CO2 incubator).
Add appropriate aliquot of FBS and antibiotic/antimycotic.
Bring to final volume.
Filter sterilize in the tissue culture hood.
