Bacteria and their byproducts can negatively affect the safety and potency of a biopharmaceutical drug. At a minimum, bioburden contaminations lead to reduced productivity as a result of lost batches and/or deviation investigations. Striving towards a bioburden-free process, biopharmaceutical companies and their suppliers must collaborate. To meet this challenge, GE Healthcare is committed to continuous improvement of its chromatography resins to enable delivery of products without detectable bioburden. For example, development of Protein A resins to withstand high NaOH concentrations…
