GCl2, 25 mM Tris, pH 7.5 and 140 mM NaCl). For pulse activation experiments, the COS-1 cells were incubated with sCD4 (40 mg/ml, 0.8 mM) or 191 (360 mM) suspended in blocking buffer for three minutes, washed three times with blocking buffer and incubated for different time periods until the C34-Ig or 48d antibodies were added (at 40 mg/ml or 1 mg/ml, respectively, for 30 minutes). To study the tem

Nan (100 /ml) for 3 h at 37 in a 5 CO2 atmosphere. Cells were washed four times and autologous stimulated T cells were added onto HIV-exposed MDDC at a DC:T-cell ratio of 1:5. Each sample was performed in triplicate. Culture supernatants were harvested every 3 days and fresh medium was added. Supernatants were inactivated with 1 Triton X-100 and frozen at -20 . The viral production by T lympho

Washing buffer (140 mM NaCl, 1.8 mM CaCl2, 1 mM MgCl2 and 20 mM Tris, pH 7.5). A horseradish peroxidase-conjugated antibody specific for the Fc region of human IgG was then incubated with the samples for 45 minutes at room temperature. Cells were washed 5 times with blocking buffer and 5 times with washing buffer. HRP enzyme activity was determined after the addition of 33 ml per well of a 1:1 mix

Ion, was used as a negative control. The YU2(Dct) protein has a truncated cytoplasmic tail of 17 amino acids, with a stop codon introduced after Ala 710 (numbered according to current convention [46]). The YU2-GS8 construct is a cleavage-defective form of the YU2 HIV-1 envelope glycoproteins that contains an 8-amino acid glycine-serine linker at the gp120/gp41 junction. Starting with the cytoplasm

Ng the 58 hitherto unreported proteins, 55 had a GO annotation and could be classified according to molecular function, cellular component, and bi-ological process (Figs. 4B, 4C, 4D). The categorization process was extended to the total (94) of proteins. Most newly identified proteins were classified into categories similar to those in the total set and included binding proteins, transporters, enz

Electronic adherence measures included overall adherence (recorded doses divided by expected doses in the monitoring period), proportions adherent above thresholds of 80 and 95 , and proportion with a 72-hour period without a recorded dose.Power Calculations and Statistical MethodsBased on our pilot experience [8], we estimated that a 20 increase in the average HIV RNA suppression
