Figure 1From: Moisture-induced solid state instabilities in α-chymotrypsin and their reduction through chemical glycosylationAggregation of lyophilized α-CT at 50°C and different RH. α-CT was dissolved at pH 7.3 and the concentration prior to lyophilization was 0.5 mg/mL. 24 h (solid circle), 48 h (open square), 96 h (open down triangle), 1 week (open triangle), and 2 weeks (solid square).Back to article page
