Safety Drives Innovation in Animal-Component-Free Cell-Culture Media Technology
Background
The development of serum-free mammalian cell-culture media technology has been impressive during the past few decades. The advances can perhaps best be appreciated when compared directl…

Ensuring Viral Safety of Viral Vaccines and Vectors
Unscreened human or animal-derived products, such as bovine serum, are now known as potential sources of bovine virus contamination (1).
Since then, better safety measures and the use of establ…
