Electron micrographs taken on Tecnai12 TEM were recorded on a 4096 by 4096-pixels charge-coupled device camera (TVIPS F416) at various nominal magnifications yielding a final pixel size between 0.25 and 0.426?nm around the specimen level. compared to a regular IgG, but the introduced linkers might still account for flexibility. We first investigated the Contorsbody with and without an anti-Fc Fab to help identifying the different moieties of the molecule by NS-TEM (Fig. 4). At such relatively low resolution, the Fc region is usually difficult to identify with certainty. Therefore, we labelled the Fc region to enable its clear discrimination from the Fabs. The anti-Fc Fab class averages decided from micrographs recorded with NS-TEM reveal the morphology of the Contorsbody. Due to preferential binding of the molecule to the carbon film,…
