Figure 4: CD spectroscopy analysis of purified C8/119S and rDer f 2. C8/119S and rDer f 2 were suspended in PBS at a final concentration of 2 mM. CD spectra were recorded from 200 to 252 nm at a digital resolution of 0.2 nm with a scan speed of 20nm/min. Gray and black lines show the average signals of eight scans of C8/119S and rDer f 2, respectively.
