RPMI 1640, with L-Glutamine, powder medium, with 25 mM HEPES, w/o Sodium Bicarbonate
Product Specifications
Storage and Shelf Life
+2 °C to +8 °C, dry and protected from light
Instructions
Preparation of 1 liter liquid medium:
- Suspend 10.0 g in 900 ml tissue culture grade water with constant, gentle stirring until the powder is completely dissolved. Do not heat the water.
- Add 3.7 g of sodium bicarbonate powder or 49.3 ml of 7.5 % sodium bicarbonate solution for 1 liter of medium and stir until dissolved.
- Adjust the pH to 0.2 to 0.3 pH units below the desired pH using 1 N HCl or 1 N NaOH since the pH tends to rise during filtration.
- Make up the final volume to 1000 ml with tissue culture grade water.
- Sterilize the medium immediately by filtering through a sterile membrane filter with porosity of 0.22 micron or less, using positive pressure rather than vacuum to minimize the loss of carbon dioxide.
- Aseptically add sterile supplements as required and dispense the desired amount of sterile medium into sterile containers.
- Store liquid medium at +2 °C to +8 °C and in dark until use.
