The map is the raw tomogram of HIV-1 BaL virus. The envelope spikes (trimer of gp120 and ecto domain of gp41, total MW is about 0.45 MegaDaltons)on the virion surface were picked up and subject to 3D alignment and classification analysis.

Highly purified virus. The envelope spikes on the virion surface are trimer. 1 NA Human immunodeficiency virus 1

The envelope spikes are distributed on the surface of HIV-1 virions.
