| Product Introduction | RPMI-1640 is an improved McCoy's 5A medium, which uses bicarbonate buffer system. RPMI-1640 medium was originally designed for lymphocyte culture. Nowadays, it has been widely used in the culture of normal cells and cancer cells, especially suspension cells, which is one of the most widely used media. RPMI-1640 medium contains many kinds of amino acids, vitamins, inorganic salts and other ingredients for cell culture, but does not contain protein, lipids or any growth factors. Therefore, the product should be used serum or serum-free additives. |

Q1:Will improper storage of my culture reagents affect the growth rate of my culture?
Yes. Store animal sera at -5 to -20℃. Store media at 2 to 8℃; use within recommended shelf life period. Store complete media (supplemented) at 2 to 8℃, and for complete medium the recommended shelf life is 3 to 6 months. Additionally, minimize exposure of sera and media to light.
Q2:Where can I find the osmolality for Medium?
The osmolality is listed in the COA for the particular lot number of the medium.
Q3:My medium was shipped at room temperature but it is supposed to be stored refrigerated. Is it okay?
We routinely ship media that require long-term storage in the refrigerator at room temperature. We have done studies on representative media formulations to show that media can be at room temperature for up to a week without a problem.
Q4:I see a precipitate in my medium, and a change in the pH. What should I do?
This is most likely a sign of bacterial or fungal contamination. We would recommend discarding the media, and trying to decontaminate the culture.
Q5:How long can I keep my media after supplementing with serum?
Generally speaking, media can be used for up to 3-6 months after supplementation with serum， at 2 to 8℃ low temperature environment preservation.
Q6:How light sensitive is media? Should I also be protecting it from LED light?
While we know that different wavelengths of light are worse than others for exposure, we would recommend as a best practice to protect the medium from all forms of light exposure including LEDs, as much as possible to ensure optimal performance, as several components within the medium are light sensitive, such as vitamins.When placed in a light-proof 4°C refrigerator with the door closed, the culture medium will be kept away from light.
Q7:Do you provide customized culture media services?
Yes. We can customize culture media with reduced components or changes in the concentration of existing components.
