FIG. 2.

gp41 ELISA. (a) The result of the IgG gp41 adsorption. The affinity-purified gp41 binding IgG fractions (pos) and the anti-gp41-depleted (neg) IgG fractions are shown for each of three different patients (Pt1 to Pt3), according to the legend on the figure. HC, healthy control; OD, optical density. (b) Graphs show lack of competition between the affinity-purified anti-gp41 serum IgG fractions and biotinylated 2F5 or 4E10. Controls are unbiotinylated 2F5 and 4E10 as well as HC IgG and HIV IG. (c) Competition between affinity-purified anti-gp41 serum IgG and anti-cluster I antibodies (2-55 and 2-378). (d) Results of the ELISAs with the 2F5 and 4E10 MPER-specific peptides. Fractions are colored as indicated on the figure.
