View larger version (49K): [in a new window]   Figure 1 (Left) Two-dimensional gel of plasma from a control volunteer using a pH range of 3 to 10. Four areas were analyzed (1 to 4) in each group of subjects. (Right) Representative bidimensional electrophoresis gel images of plasma from patients during acute myocardial infarction (AMI), unstable angina (UA), and age-matched control subjects using a pH range of 4 to 7. Albumin was identified in area 5 and was used to normalize total spot volume in each of the other areas.

Images were obtained from the bidimensional electrophoresis gels using a pH range of 4 to 7. Numbers 1 to 7 were only used to identify each AAT isoform.

Images were obtained from the bidimensional electrophoresis gels using a pH range of 4 to 7. Numbers 1 to 3 were only used to identify each fibrinogen gamma chain isoform.

Images were obtained from the bidimensional electrophoresis gels using a pH range of 4 to 7. Numbers 1 to 5 were only used to identify each apolipoprotein A-I isoform.
