Accelerated Forced Degradation of Therapeutic Peptides in Levitated Microdroplets.

The accelerated forced degradation method requires a minimal amount of therapeutic peptide per stress condition, and the appropriate extent of degradation can be readily generated in seconds by adjusting the droplet levitation time. Levitated microdroplets should be applicable in pharmaceutical development to rapidly determine the intrinsic stability of therapeutic peptides and to aid formulation development by screening the effects of excipients on the stability of the peptides.
