Abstract

The prevention of adventitious agent contamination is a top priority throughout the entire biopharmaceutical production process. For example, although viral contamination of cell banks or cell cultures is rare, it can result in serious consequences (e.g., shutdown and decontamination of manufacturing facilities). To ensure virus free production, numerous in vivo and in vitro adventitious agent assays and biophysical characterizations such as electron microscopy are conducted on cell banks, raw materials, process materials, and drug substances throughout the manufacturing process. Molecular assays such as PCR and other nucleotide‐based techniques are also routinely used for screening and identification of any viral agents. However, modern techniques in protein identification of complex protein mixtures have not yet been effectively integrated throughout the industry into current viral testing strategies. Here, we report the identification and quantitation of Vesivirus 2117 particles in bioreactor fluid from infected Chinese hamster ovary cell cultures by global protein sequencing using mass spectrometry in combination with multi‐dimensional liquid‐chromatography. Following mass spectrometric data acquisition and rigorous data analysis, six virus specific peptides were identified. These peptides were fragments of two structural proteins, capsid protein pre‐cursor (four unique peptides) and small structural protein (two unique peptides), from the same species: Vesivirus 2117. Using stable heavy isotope‐labeled peptides as internal standards, we also determined the absolute concentration of Vesivirus particles in the bioreactor fluid and the ratio of two capsid proteins (VP1:VP2) in the particles as approximately 9:1. The positive identification of Vesivirus 2117 was subsequently confirmed by RT‐PCR. Biotechnol. Bioeng. 2013; 110: 1342–1353. © 2012 Wiley Periodicals, Inc.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Vesivirus 2117 contamination of CHO-cell bioreactors at Genzyme caused significant financial losses and delayed drug delivery to patients with Gaucher or Fabry disease.

    “Vesivirus 2117 has caused significant financial losses owing to the contamination of bioreactors at Genzyme (Allston Landing and Geel facilities) where CHO cells were used for the production of biopharmaceuticals.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
