FAQs - Cell Culture Media
A primary cell line is produced from a single cell type isolated from tissue and cultured under optimal and controlled conditions.
Cell medium ingredients include nutrients (both organic and inorganic), vitamins, salts, O2 and CO2 gas phases, proteins (from defined or undefined sources), carbohydrates, cytokines, growth factors, and cofactors.
Media should be changed every 2 to 3 days. However, media is best changed when cell density reaches a healthy level, so this also depends on the growth rate of your cell culture. Most media also contain a pH indicator that changes color to yellow when pH drops, which is a sign of nutrient depletion and waste accumulation.
- Serum-containing media - basal media supplemented with undefined biological materials such as serum or cell extracts.
- Serum-free, animal component-containing media - basal medium supplemented with defined proteins, growth factors, and cytokines from animal sources;
- Serum-free, xeno-free medium - basal media supplemented with defined proteins, growth factors, and cytokines from human origin only.
- Animal component-free, chemically defined medium - basal medium composed of material from chemically defined sources.
Cell culture medium provides nutrients and growth factors necessary for cell proliferation. A typical basal cell culture medium is composed of amino acids, carbohydrates, vitamins, inorganic salts, glucose, trace elements, and a buffer system to maintain a stable pH. Traditionally, animal-derived serum is used to supplement basal media to provide a source of growth factors. Now, serum-free, chemically defined formulations are highly favored.
Serum-free media are media designed to grow cells in the absence of animal-derived serum. Serum-free media include chemically defined media, which are free of any animal components or hydrolysates.
Serum-free media allows cell culture to be performed under a defined set of conditions, limiting batch-to-batch variability. It also simplifies purification and downstream processing.
Xeno, derived from the Greek word “xenos”, means “foreigner.” A xeno-free media is a culture medium with a formulation that only contains human-derived components and not any other species such as bovine or porcine.
Serum-free media are free from any serum (from all animal species) but can include other animal components (such as HSA and BSA), while xeno-free is free of components from non-human animal species but can include human serum.
Each medium should be stored according to the manufacturer’s protocols and recommendations. Most basal media require storage under controlled conditions at 2-10°C, light protected, and secured to avoid degradation and contamination of the components. Once opened and supplemented with additional components under sterile conditions, the medium can typically be stored for 1-4 weeks at 2-8°C and light protected.
Each medium should be stored according to the manufactured protocols and recommendations. The typical expiration date is within 12-18 months of manufacture. When open and supplemented with other components under sterile conditions, media can generally be stored for 1-4 weeks, at 2-8°C, and protected from light. Classical media supplemented with serum antibiotics can be kept at 4°C for up to 4 weeks; serum-free media can be kept for up to 2 weeks.
Bleach should be added to unused media at ≥10% final concentration to treat any microorganism present before disposal.
