Identification of Levels of Serum Amyloid A and Apolipoprotein A1 in Serum Proteomic Analysis of Neuropsychiatric Systemic Lupus Erythematosus Patients

Figure 1

Two-dimensional gel electrophoresis image showing the two protein spots that were consistently increased or decreased in NPSLE patients compared to the other groups. The encircled spots resulted differentially expressed in the high abundance fraction. The calculated molecular weights (MW) and isoelectric points for spot 4009 were 20,9 kDa and pH = 5,9, respectively and for spot 8001 were 6,1 kDa and pH =6,5. The square shows the landmark used for matching 2D images for the comparative analysis. MW: molecular weight in kDa.
