Extended Data Figure 2. Initial single-particle cryo-EM study of hTRPA1.
a, Raw micrograph of MBP-hTRPA1 recorded using a scintillator-based CMOS camera. b, 2D class averages of MBP-hTRPA1 particles. c, Euler angle distribution of initial 3D reconstruction. d, FSC curve of final 3D reconstruction. e, Final 3D reconstruction of MBP-hTRPA1 at 28Å resolution. This 3D reconstruction was used as the initial model for subsequent cryo-EM studies of hTRPA1 using a direct electron detection camera.
