FIG. 3.
ELISA binding curves of select anti-gp120 Abs against full-length and loop-deleted constructs of gp140JR-FL. Full-length (diamonds), V1-deleted (squares), V2-deleted (triangles), and V3-deleted (x) gp140JR-FL were captured via the C-terminal region of gp120 with the sheep Ab D7324 and probed with pooled HIVIG, 2G12, Fab AH48, G3-4, G3-519, G3-42, G3-299, and 4KG5. The detection reagents were ABTS for 4KG5 and AP staining solution for all other Abs.
