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…

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
Replacing complex bovine serum supplements with purified bovine proteins such as albumin, insulin, transferrin, and fetuin was seen as a major advantage in the early days of serum-free media technolog…

Implications of Cell Culture Conditions on Protein Glycosylation
An example of this can be seen in the N-glycans released from bovine fetuin, as shown in Figure 2. This method gave consistent data across three preparations, a series of clustered peaks representing …

Application of Quality by Design to Viral Safety
For instance, massively parallel sequencing has been used to evaluate bovine serum, and this testing helped distinguish bovine adeno-associated virus (BAAV-2) as a new contaminant (5). Once a panel of…
