FIG. 4.
Competition ELISA. Plates were coated with HveC(346t) and incubated with a constant amount of purified gD, together with increasing concentrations of HveC truncated receptors as competitors. Panels show 1 μM gD-1(306t) from HSV-1 KOS (A), 0.1 μM gD-1(rid1t) (B), and 1 μM gD-2(306t) from HSV-2 strain 333 (C). gD bound to the immobilized receptor was detected with R7 antiserum. Relative binding is indicated as percentage of gD binding in the absence of soluble receptor.
