FIG. 2.

Inhibition of the binding of purified human anti-Id antibodies (Ab2) to anti-gp43 MAb 17c by purified human anti-gp43 antibodies. Binding of 0.25 to 10 μg of anti-gp43 MAb 17c per ml to purified human anti-Id antibody (Ab2)-coated plates was measured in the absence or presence of purified human anti-gp43 antibodies. Data were obtained from a representative patient. Assays were done in duplicate. Error bars show standard deviations. O.D., optical density.
