From: Discrete partitioning of HIV-1 Env forms revealed by viral capture
Native-PAGE determination of the Env conformations present after virus depletion. a Purified HIV-1BaL virions were depleted by the antibody specified and separated on native-PAGE gels and western blots were probed with a gp41 (2F5, 4B3, 3D6) or gp120 (b12, 2G12, b6) antibody cocktail. The abundance of Env species were quantified relative to undepleted virus for blots probed with (b) gp120 antibodies or (c) gp41 antibodies. Blot is representative of at least 3 independent depletion experiments and quantification is the average of 3 images
