Are there better quality FBS origins (sources) than others?

To the best of our knowledge, the serum’s origin has no influence on cell growth. Commonly, one lot of fetal bovine serum (FBS) may exceed the control of a specific cell line but not for another. Serum quality is specific for each cell line and can vary. These variation may include (but not limited) to: Geographical location, the time of year the blood was collected and dietary factors etc. Peak Serum strongly encourages our customers to test prior to purchasing to ensure total satisfaction.
