Figure 3 Sucrose gradients of sera of responders A and B (A,B) and of non‐responders C and D (C,D). The measured radioactivity in the fractions as a percentage of the maximum radioactivity at each time point (% of maximum) is shown. The values on the y axis in D have been adjusted to the lower amounts of radioactivity in the 30‐min sample to visualise the size of the antibody complexes in this patient.
