Fig. 2. oxLDL-pull down experiments from blood of patients with severe atherosclerosis using protein G Sepharose-bound Fc-CD68 fusion proteins. Serum of atherosclerotic patients was applied to Fc-CD68 affinity resin collums and oxLDL content was measured before (serum) and after column application using a commerially available oxLDL/MDA adduct ELISA. The relative values [in %] compared to oxLDL levels in untreated serum as single data points and the Means ± SEM of 7 independent experiments with different patient sera are shown. Each measurement was performed in duplicates. * indicated statistical significance of p<0.05 compared to oxLDL in untreated serum.
