What is fcs biology

You must swirl the bottles to mix the serum every 5 minutes during heat inactivation to insure uniform heating. Use a calibrated thermometer only! As a result of improper heat inactivation of the serum temperature above 56oC, more than 30 minutes , or inactivation without mixing the serum, a protein denaturation caused the jellylike fraction on the bottom of the bottle.

Do not use this serum. We recommend thawing the serum at oC. However, if necessary, you may thaw the serum at room temperature. Swirl the bottles gently to mix the serum during the thawing process. The color of FBS is brown to brown-red. It is dependent mainly on the hemoglobin concentration in the specific lot. The color does not affect the FBS performance.

Deformation does not affect the FBS quality and performance. Cookie Policy This website uses cookies to ensure proper functionality of the shopping cart and checkout progress. Accept Decline. Contact us. Biological Industries. Our History.

Furthermore, users can add information on missing media directly to the website, making it not only an information source for, but also by scientists. While FCS is treated as having almost universal application, chemically-defined media are cell-type specific, meaning that for every cell type used a new medium needs to be developed.

One significant challenge in developing chemically-defined media as alternatives to FCS is the sheer number of cell types in use — almost , according to the Cellosaurus database as of July This is also a big challenge for the FCS-Free Database, but we have succeeded in bringing attention to this issue and creating an effective way for researchers to find and share information on alternatives.

To avoid the use of FCS in the short term when no defined medium is available, human platelet lysates hPLs could be considered as a supplement, particularly when working with human cells.

Still, as a biological product, they also differ from batch to batch 8. The development of a defined medium for a specific cell type may seem a tedious exercise, but appropriate experimental design via the use of a design matrix can allow for multiple components to be varied within the same experiment.

This not only shortens the development time, but also takes factor interactions into account 9. A crucial step that should not be ignored is the adaptation of cells to the new medium. Although its role is not fully understood — whether cells really adapt or sub-cloning occurs — it seems crucial for most cells to thrive in the new medium. The search for defined media is not new: it began in when Harry Eagle identified the crucial amino acids, vitamins, salt and glucose needed for effective cell culture 10 , and has continued since.

The subsequent widespread use of FCS and its relative success in in vitro research has likely slowed down research into serum-free alternatives considerably. Skip to main content.
