    Concentrationreconstituted to various nominal concentrations in DMSO

Procedure

Pramlintide acetate was dissolved in H2O at 2 mg/mL with either a 10 mM citrate buffer, pH 4 or 10 mM phosphate buffer, pH 7. These solutions were lyophilized to dryness (>1% residual moisture) using a conservative cycle and reconstituted to various nominal concentrations in DMSO. Solubility was measured by visual inspection for clarity and turbidity via A630.
