Precipitation of HIV-1 Gag Δp6 with oligonucleotides of different lengths, sequences, and oligonucleotide/protein ratios. Assembly reactions with oligonucleotides of different lengths (10, 15, 20, 25, or 30 nt long) and at different oligonucleotide/protein ratios (0, 1, 2, 4, 8, or 16% [wt/wt]) were performed and the products analyzed as described in the legend to Fig. 3. The percentage of protein in each pellet fraction was quantitated by densitometry. (A) Poly(dA) oligonucleotides; (B) poly(dTG) oligonucleotides.
