Figure 2. Far-ultraviolet circular dichroism spectra of recombinant wild-type and mutant transforming growth factor beta-induced protein.A: Far-ultraviolet circular dichroism (far-UV CD) spectra of recombinant transforming growth factor beta-induced protein (TGFBIp). The protein concentrations were 0.1 mg/ml. B: The concentration-dependent conformational changes of wild-type (WT) TGFBIp. The far-UV CD spectra of WT TGFBIp were measured at 0.1, 0.2, 0.4, 0.8, 1.6, and 3.2 mg/ml.
