$Fig. 1. Retention of APC on protein A columns to which control IgG (▪) or patient’s IgG (◂) were adsorbed. A total of 200 μL of APC (200 ng) in TBS-BSA was applied to the respective protein A-IgG columns and fractions of 250 μL were collected and assayed for APC activity as outlined in Materials and Methods. The results are expressed as percent of the APC concentration applied to the column.$
