Figure 1. The direct and loop transfer methods.

Figure 1

(A) Teflon block used to grow 2D crystals on lipid monolayers. (B, C) Direct transfer method, after which the lipid monolayer is in contact with the carbon film. (D, E) Loop transfer method, after which the protein crystal is in contact with the carbon film. For (B – E) Protein crystals are in yellow while the EM grid is colored gold.
