4 uL of sample was applied to a freshly plasma-cleaned thin carbon surface that was pre-treated with 0.1% w/v poly-L-lysine hydrobromide. After removing excess protein, negative staining was performed with 2% w/v uranyl formate solution.

Processing leading up to 3D reconstruction was performed using the Appion package. Particles were selected from micrographs using an automated template-based particle picker. The stack was subjected to five iterations of iterative 2D alignment and classification using multivariate statistical analysis (MSA) and multi-reference alignment (MRA). The clean particle stack was subsequently subjected to 3D refinement by iterative projection matching using EMAN2 and SPARX libraries.
