Electron microscopic images of fractionated Wnt3a. a–c EM images of unfractionated sample (a), sample eluted in void volume (b), and sample recovered in fraction 14 (c). The scale bar in a–c represents 500 Å. d–f Image of Wnt3a reconstructed by single-particle analysis. Top view (d), oblique view (e), and side view (f) are shown. The volume enclosed by the isosurface is 100% (cyan) and 150% (dark blue) of the volume estimated from the molecular weight of the Wnt3a trimer
