Fetal Bovine Serum, ES Cell Qualified

This serum is tested for ability to support the growth and maintenance of embryonic stem cells in an undifferentiated state. Undifferentiated embryonic stem cells are determined by colony morphology and expression of three pluripotent markers. The results are compared to a control lot of serum. The serum is triple filtered through 0.1µM filters and each lot of fetal bovine serum is tested for sterility. Fetal bovine serum is manufactured from fetal bovine blood collected in USDA inspected abattoirs located in the United States.

General Procedure: Fetal Bovine Serum, ES Cell Qualified is added to Mouse ES Basal Cell Media to a final concentration of 10 to 15%.

If you are not using all of your thawed serum at once, dispense it into single-use aliquots and store these at -70°C or -20°C. Protect the aliquots from light as much as possible during storage.

Serum Precipitates
Turbidity and flocculent material may be present after thawing. ATCC’s experience indicates that neither of these changes affect the performance of serum. If the presence of flocculent material or turbidity is a concern, they can be removed by aseptic filtration through a sterile 0.45 µm filter.

Heat-Inactivation of Serum

CAUTION: Heat-inactivation of serum is usually unnecessary and can be detrimental to the growth of some cells. We strongly recommend that you heat-inactivate fetal bovine serum only if it is required for a particular cell line.

1. Thaw serum following the directions above.
2. Preheat a water bath to 56°C with sufficient water to rise above the level of the serum in the bottle.
3. Mix thawed serum by gently swirling the bottle and then place the bottle in the 56°C water bath. (The temperature of the water bath will decrease.)
4. When the temperature of the water bath reaches 56°C again, heat the serum for an additional 30 minutes. Mix gently every five minutes to ensure uniform heating.
5. At the end of 30 minutes, remove serum from the water bath, cool, and store at -70°C or -20°C (see Storage, above).
