WebbThe stability of three commercial “fast‐acting” insulin analogs, insulin lispro, insulin aspart, and insulin glulisine, was studied at various concentrations of phenolic preservatives (phenol and/or meta‐cresol) during 9 days of incubation at 37°C. The analysis by both size‐exclusion and reversed‐phase chromatography showed degradation of lispro and … WebbCorrespondingly, IgG4-N1 showed a moderately increased Tm (38.9 ± 0.3°C) compared to that (34.3 ± 0.1°C) of the control condition. The results demonstrate that protein stability modifiers such as mannitol can effectively reduce aggregation formation in low-pH VI. This protein stabilizing effect of mannitol agrees well with other reports.
