Figure 2.
The selenylsulfide peptide is stable to serum proteases. Peptides 2a-c were incubated in the presence of 50% mouse serum over a time course of 12 hours. Degradation was monitored by LC-MS. The 280 nm absorbance of each peptide and their corresponding degradation products was measured. Degradation was measured as compared to the initial time point. Error bars represent SD.
