Product Introduction
Background
DMEM (Dulbecco's Modified Eagle Medium) was developed on the basis of MEM medium. Compared with MEM medium, the content of amino acid increased by 2 times, the content of vitamin increased by 4 times, and the content of non-essential amino acid, trace iron ion and sodium pyruvate were increased by 4 times. The glucose content of DMEM medium was originally designed as 1000 mg/L (low Glucose type), and then developed into 4500 mg/L (high Glucose type), which has been widely used in cell culture.
DMEM (High glucose) was widely used in fast growth, low adhesion cells, hybridoma myeloma cells, clone cells, DNA transfected transformation cells, various primary virus host cells, single cell culture and vaccine production.
DMEM (High glucose) 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, so the product should be used with serum or serum-free additives.

FAQs
-
Q:1 What temperature should be used when preparing liquid medium from dry powder medium?
AnswerDuring the preparation of liquid medium from dry powder medium, dissolution is typically carried out at room temperature (approximately 20–30 °C). This temperature range is sufficient to ensure proper dissolution without compromising the stability of the medium components.
-
Q:2 Are there any specific requirements for the sodium bicarbonate used when preparing powdered culture media?
AnswerAnalytical-grade sodium bicarbonate is sufficient. Please note that after preparation, the powdered culture medium should be filter-sterilized.

Q:3 Why do we need to add sodium bicarbonate to dry powder culture medium? Can’t we add it to the dry powder in advance and dissolve it directly during preparation?
AnswerSodium bicarbonate (NaHCO3) in cell culture medium is usually not included in the dry powder form of culture medium, but is added as a separate component during the preparation of culture medium solution. The main reasons include: 1. Sodium bicarbonate is easy to decompose under certain conditions and is sensitive to carbon dioxide. If it is pre-mixed into dry powder culture medium, it may affect its stability and cause the effective ingredients to fail. 2. Since the carbon dioxide concentration in different laboratories and the specific conditions (such as temperature and time) of the operator during preparation may be different, sodium bicarbonate is added during the final preparation of liquid culture medium. Its concentration can be adjusted according to actual needs to ensure that the culture medium reaches the ideal pH value. 3. Storing sodium bicarbonate separately can also facilitate the transportation and long-term storage of dry powder culture medium, because sodium bicarbonate may cause caking when it is damp, affecting its solubility.

Q:4 How much temperature control is needed during the preparation of liquid media from dry powdered media?
AnswerDissolving can be controlled at room temperature (20-30°C).
