Fig. 4. LC variable domains form amyloid-like fibrils under native-like conditions, while full-length LCs form amorphous aggregates at high temperature.
Representative electron micrographs of aggregates formed by 20 μM ALLC-V (a) and 20 μM JTO-V (b) at 37 °C, 250 rpm in PBS, pH 7.4 for 48 h. Aggregates formed by ALLC-FL (c) and JTO-FL (d) at 55 °C in PBS, pH 7.4 for 96 h are amorphous. Scale bars = 0.2 μm. Both conditions result in the formation of amorphous aggregates, but only the V-domains additionally form amyloid fibrils.
