SKU: AT171-10X1L
HIMEDIA RPMI- 1640 w/ 2mM L-Glutamine, 1mM Sodium Pyruvate 4.5gms Glucose per litre and 10mM HEPES buffer w/o Phenol red and Sodium bicarbonate 10X1L, 20L
Product Description :
Roswell Park Memorial Institute (RPMI) media are a series of media developed by Moore et.al for the culture of human normal and neoplastic cells in vitro. RPMI-1640 is the most commonly used medium in the series. A modification of McCoy's 5A medium, the
medium was specifically designed to support the growth of human lymphoblastoid cells in suspension culture. Presently the medium is extensively used for a wide range of anchorage dependant cell lines. The medium needs to be supplemented with 5-20%
fetal bovine serum. The medium is also known to support growth of cells in the absence of serum.
AT171 is RPMI-1640 with 2mM L-Glutamine, 1mM sodium pyruvate, 4.5gms per litre glucose and 10mM HEPES buffer. It does not contain phenol red and sodium bicarbonate. HEPES, a zwitterionic buffer having a pKa of 7.3 at 37 ºC prevents the initial rise in pH that tends to occur at the initiation of a culture and increases the buffering capacity of the medium. Users are advised to review the literature for recommendations regarding medium supplementation and physiological growth requirements specific for different cell lines.

Directions :
- Suspend 15.4gms in 900ml tissue culture grade water with constant, gentle stirring until the medium is completely dissolved. Do not heat the water.
- Add 2.0gms of sodium bicarbonate powder (TC230) or 26.7ml of 7.5% Sodium bicarbonate solution (TCL013) and 10.3ml of 200mM L-glutamine solution (TCL012) for 1 litre of medium and stir until dissolved.
- Adjust the pH to 0.2-0.3 pH units below the desired pH using 1N HCl or 1N NaOH since the pH tends to rise during filtration.
- Make up the final volume to 1000ml with tissue culture grade water.
- Sterilize the medium immediately by filtering through a sterile membrane filter with a 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 2-8°C and in dark till use.
