Concerns about the potential for prions to be retained on chromatography gels during the manufacture of plasma products prompted development of an investigational strategy for detecting infectious prions bound to gels. The objective was to firstly examine methods of implanting gels intracerebrally (IC) in mice, then to examine prion cleaning from a scaled-down version of the DEAE Sepharose colu…
Although there is no epidemiological evidence to suggest that classical Creutzfeldt–Jakob disease (CJD) is transmitted through blood or blood products, the variant form (vCJD) has been implicated in transmission via packed red blood cells. The potential threat of the infectious agent contaminating plasma pools has led to manufacturing processes being examined for capacity to remove prions. Th…
