Overview

Avoid inadvertently studying bovine exosomes

Fetal bovine serum, or FBS, is an important component of many types of cell culture media. But for researchers interested in isolating exosomes from cultured cells, standard FBS can introduce unwanted complications—bovine exosomes, which can cause significant background issues or interfere with functional studies. Which is why SBI developed Exo-FBS, our patented exosome-depleted FBS.

• Exosome-sized vesicles removed
• Very low levels of CD63-positive bovine exosomes
• Undetectable levels of bovine miRNAs
• Comparable growth rates as standard FBS
• Interchangeable with standard FBS (add 10% in DMEM or RPMI)
