Thus, the presence of other forms of toxicity (metals and organics) in the sample may be masked by the toxic effects of low or high pH.
The pellets from the ammonium sulfate fractionation were resuspended in 60 ml of buffer B (20 mM HEPES pH 8.5 4°C, 1 mM EDTA, and 0.1% 2-mercaptoethanol), desalted on a G-25 sephadex column equilibrated with buffer B, then subjected to sequential chromatography on a 5 ml HiTrap Heparin column (Pharmacia), a 5 ml HiTrap Q column (Pharmacia) and a HiTrap SP column (Pharmacia) respectively.
The digested PCR products were resolved in either 2% or 2.5% agarose electrophoretic gels in 1 × TAE buffer (40 mM Tris-acetate, 1 mM EDTA pH 8.0) and visualized by ethidium bromide staining.
To confirm that gp41 six helix bundle formation was caused by contact of virus particles with the micronized form of CAP (= Aquateric) and not by low pH contributed by CAP, purified HIV-1 III B and BaL, respectively, was exposed for 5 min at 37°C to acidic buffers (final pH 2.9, 3.5, 4.0, 4.5 and 5.0).
For each set of heterodimers, 260 μg of p51 was mixed with 660 μg of p66 in the buffer containing 50 mM Tris HCl, pH 7.8, 60 mM KCl and 5 mM MgCl 2 . The rationale for using a 1:3 ratio of p51 to p66 was to saturate the His-tagged p51 with the non-tagged p66, ensuring heterodimer formation and eliminating excess p66 during IMAC purification.
