An Integrated Approach to Ensure the Viral Safety of Biotherapeutics
Although several serum-free and chemically defined nutrient media formulations are available for commercial use, many cell-culture applications require use of nutrient media supplementation with serum…

Ensuring the Biological Integrity of Raw Materials
For example, bovine serum can be contaminated with reovirus, epizootic hemorrhagic disease virus, Cache valley virus, or Vesivirus 2117. Porcine circovirus is sometimes found in porcine trypsin. Minut…

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…
