What is a serum-free medium?
What is a serum-free medium?
Serum-free media are media designed to grow a specific cell type or perform a specific application in the absence of serum. The use of serum-free media (SFM) represents an important tool, that allows cell culture to be done with a defined set of conditions as free as possible of confounding variables.
What is serum medium?
Serum is vitally important as a source of growth and adhesion factors, hormones, lipids, and minerals for the culture of cells in basal media. In addition, serum also regulates cell membrane permeability and serves as a carrier for lipids, enzymes, micronutrients, and trace elements into the cell.
What is serum-free culture?
Serum-free media (SFM) allow researchers to grow a specific cell type or perform a specific application in the absence of serum.
Why is serum-free media better?
Serum-free media offer several basic advantages over serum-containing media. The simplified composition is better defined than that of serum- based media. Contaminants are reduced, and a potential source of infectious agents is eliminated. Serum-free media can be a more economical choice (2).
What are the disadvantages of serum?
The disadvantages of serum are described, including variability, shelf life, availability, effect on down-stream processing, and potential for contamination.
Is RPMI serum-free?
RPMI 1640 has traditionally been used for the serum-free expansion of human lymphoid cells. RPMI 1640 uses a bicarbonate buffering system and differs from most mammalian cell culture media in its typical pH 8 formulation.
What is the disadvantage of serum?
Why does Dmem turn pink?
Popular Answers (1) DMEM contains phenol red, which is solely a pH indicator. At physiological pH, the media is a pink-red color. Additionally, DMEM is a bicarbonate buffered system, which relies heavily on this CO2 concentration.
Can cell grow without serum?
To successfully grow cells in serum-free medium is an interesting challenge to cell biology. Two epithelial cell lines, LLC-PK1 and Caco-2, were progressively adapted to a special culture medium containing 10% Prolifix in the absence of serum. After adaptation, cell cultures were characterised.
What is the advantages and disadvantages of serum-free media?
Table 1.
| Advantages of serum in media | Disadvantages of serum in media |
|---|---|
| Serum contains various growth factors and hormones which stimulates cell growth and functions. | Lack of uniformity in the composition of serum |
| Helps in the attachment of cells | Testing needs to be done to maintain the quality of each batch before using |
What are the advantages and disadvantages of serum-free medium?
What are the advantages and disadvantages of serum-free media in cell culture?
- Increased definition and more reproducible formulations, allowing for more convincing and consistent research results.
- Easier purification and downstream processing.
- Lower risk of contamination with bacteria, fungi or virus.
What is the function of serum?
The human serum is a circulating carrier of exogenous and endogenous liquids in the blood. It allows substances to stick to the molecules within the serum and be buried within it. Human serum thus helps in the transportation of fatty acids and thyroid hormones which act on most of the cells found in the body.
What does it mean to have serum free media?
A serum-free formulation, by definition, means the absence of serum. How ever, within this definition there are various possibilities and classifications. Figure 8.1 serum to serum-free media with various characteristics.
Is there a serum free medium for MSCs?
Commercial serum-free medium. A commercial serum-free medium developed for expansion of human MSCs was purchased from RoosterBio (Frederick, MD). The composition of this media is proprietary and was not available to the authors. Formulation of serum-free medium in our laboratory.
Which is a serum-free medium formulation efficiently supports?

How to search for serum free cell culture?
Searches for serum-free media and continuous cell lines already adapted to serum-free culture can be performed according to various criteria.
