Figure 1From: Identification of host proteins associated with HIV-1 preintegration complexes isolated from infected CD4+ cellsExperimental design for the identification of host proteins associated with HIV-1 PIC. The PICs were generated following a protocol described previously [5]. PICs covalently bound to biotinylated DNA were isolated using streptavidin beads. The proteins in the isolated complex were identified by mass spectrometric analysis. PMA: phorbol 12-myristate 13-acetate.Back to article page
