Fig. 6: gdPT has increased thermostability compared to PTx.

a Thermal denaturation of gdPT and PTx was studied by collecting the SYPRO Orange extrinsic fluorescence as a function of temperature. b A significant increase in the thermostability of gdPT in comparison with PTx was observed with a ΔTm = 2.1 °C (Student’s t test, p < 0.0001, n = 3 independent experiments).
