الإجراء التجريبي
Glucagon acetate was prepared at 1.0 mg/mL via dissolution in 2 mM L-glycine, pH 3.0 (titrated with concentrated HCl). The glucagon formulations were lyophilized and reconstituted in DMSO at a nominal concentration of 5 mg/mL glucagon. Solution samples were divided and trehalose was added to one solution to a concentration of 5%. These formulations were aliquoted into vials and placed in a stability incubator at 5° C. At 5° C., these solutions were observed to freeze. The glucagon solutions were thawed at various interals and turbidity was determined using the absorbance at 630 nm.
