Challenges in OBP Product Review• Variety of Cell Substrates• microbiology (virus, prion), host cell molecules• Heterogeneity• glycosylation, oxidation, PEGylation• Higher order structure : structure/function
• receptor interaction and signaling• Manufacturing Issues• scale-up, solubility, aggregation• Mechanism of Action: sometimes unclear• design of bioactivity/potency assays• Immunogenicity: • safety and efficacy Issues• Comparability: manufacturing changes• Counter Bioterrorism: Animal Rule, stockpiles
