Sterility tests are performed on each lot of fetal bovine serum using current USP and EP methods. Specific tests for contaminants are listed below in the Specification Certificate.  ATCC also checks each lot for its ability to support the growth of several different cell lines.

ES Cell Qualified (ATCC^® SCRR-30-2020) serum, which is tested for its ability to support the growth and maintenance of embryonic stem (ES) cells in an undifferentiated state, is also available. Undifferentiated embryonic stem cells are determined by colony morphology and expression of three pluripotency markers.

Origin
This fetal bovine serum is manufactured from fetal bovine blood collected in USDA-inspected abattoirs located in the United States.
