چکیده

Arginine (Arg) is a commonly used additive to prevent protein aggregation and inactivation in denaturing solutions. This paper presents new findings on the synergistic effect on the prevention of heat-induced aggregation of lysozyme using Arg in combination with polyethylene glycol (PEG). The synergistic enhancement was observed in the presence of Arg with amphiphilic polymers, such as PEG6000, PEG20000, and poly(vinyl pyrrolidone), while it was not observed with hydrophilic polymers, such as PEG200, Poly(acrylic acid), poly(vinyl alcohol), dextran, and Ficoll 70.

Study on the Effect of Solution Conditions on Heat Induced-Aggregation of Human Alpha Interferon

A major problem in the formulation of therapeutic proteins is the irreversible protein aggregation. Recombinant human interferon alpha2b (rhIFN2b) has poor stability and undergoes physical degradation. The aim of this study was to investigate the effect of solution conditions on the heat-induced aggregation of rhIFNα2b. The protein was incubated for 1 h at 40°C–70°C and for up to 240 h at 50C...
