Proteomic Analysis of Plasma-Purified VLDL, LDL, and HDL Fractions from Atherosclerotic Patients Undergoing Carotid Endarterectomy: Identification of Serum Amyloid A as a Potential Marker

Figure 2

Relative amounts of exchangeable apolipoproteins in VLDL (a), LDL (b), and HDL (c) fractions representative of both patients and controls. Data were obtained by image analysis on 2-DE maps from all examined pooled plasma samples (4 obtained from patients and 4 from healthy controls) using PD-Quest analysis software V 8.0.1. Because of its high percentage in respect to the other apolipoproteins, apo AI was omitted in the panels corresponding to LDL (b) and HDL (c) fractions, being 72.9±9.8% and 91.5±3.7%, respectively. Relative amount of AP SAA is reported in Figure 3. Data are expressed as mean ± SD.
