Isothermal titration calorimetry data for DR4 or DR5 binding to TRAIL. (a) 80 µM DR4 titrated into 4.7 µM TRAIL. (b) 80 µM DR5 titrated into 1.6 µM TRAIL. (c) Overlay of ITC binding isotherms for titrations of 80 µM DR4 versus 4.7 µM TRAIL (black), 150 µM DR4 versus 4.7 µM TRAIL (red), 80 µM DR5 versus 3.1 µM TRAIL (blue) and 80 µM DR5 versus 1.6 µM TRAIL (green). (d) Differential scanning calorimetry thermograms showing the thermal denaturation of DR4 (black), DR5 (blue) and TRAIL (red). |
