PLOS PATHOG. 9 e1003618 e1003618 2013 24068931 doi:10.1371/journal.ppat.1003618 HIV spike protein 664G construct in complex with sCD4 and Fab fragment of 17b monoclonal antibody HIV spike protein 664G construct in complex with sCD4 and Fab fragment of 17b monoclonal antibody
The sCD4 was incubated for 1h at 4C with BG505 SOSIP.664. After, this complex was incubated for 40 minutes at 4C with 17b. Finally, this complex was purified using size exclusion chromatography and concentrated.

Particles were picked automatically using DoG Picker and put into a particle stack using the Appion software package. Initial, reference-free, two-dimensional (2D) class averages were calculated using particles binned by five via the Xmipp Clustering 2D Alignment and sorted into classes. EMAN was used for the 3D reconstruction.

The particles were selected using a DoG Picker, and cleaned using reference-free class averaging. The final map was calculated from a single dataset.
