Embryonic stem (ES) cell screened FBS is tested by experienced ES cell culturists for plating efficiency, colony morphology, and toxicity tests.

Research using embryonic stem (ES) cells continues to increase, and serum suitability is critical for keeping these cells in their valuable undifferentiated state. Historically, researchers have screened several lots of serum to find one suitable for ES research. ES Screened FBS from Biowest potentially eliminates the need for prescreening serum, saving both time and money, while providing the assurance that the serum used has been screened by experienced ES cell culturists. Lot reservation is available for ES Qualified FBS. Contact your local USA Scientific representative or infoline@usascientific.com to request a sample for lot testing.

Biowest Fetal Bovine Serum is rigorously tested for sterility and the absence of mycoplasma, specific viruses, bacteria, and fungi. During performance testing, cultures are examined microscopically for cell growth, plating efficiency, cloning efficiency, and morphological abnormalities. Low endotoxin and hemoglobin levels are additional key indicators of the advanced sourcing and processing protocols.

Large lot sizes are available. If you have limited storage space, ask about our reserve program. Manufactured to comply with GMP guidelines. Raw materials are from EC approved sources and are USDA approved.
