FIG. 3.

Comparison of gD binding to HveCt and HveAt. ELISA plates coated with HveCt or HveAt at 200 nM in PBS were incubated with increasing concentrations of gD(306t). Bound gD was detected with antiserum R7 followed by peroxidase-conjugated secondary antibody and substrate. Absorbance was read at 405 nm.
