Fig. 2. Influence of heating on the structure and folding of epitope-bearing Q11.

Fig. 2

The structure and mass of epitope-bearing peptide fibers were not significantly altered by heating at 45°C for 7 days. MALDI mass spectra of OVA-Q11 (a) and ESAT-Q11 (b) were similar between unheated and heated samples (OVA-Q11 [M+H]+ m/z calc’d 3529; ESAT-Q11 [M+H+] m/z calc’d 4035). Expanded m/z ranges shown in Supplemental Fig. 1. Nanofibers were formed by OVA-Q11 and ESAT-Q11 peptides before and after heat treatment (c, TEM, scale bar 100 nm for all images).
