Principle component analysis of gene expression showing distinct clusters between individual immune cell subsets but not between the same subsets derived from PBMC isolated by CPT or Ficoll protocols. Principle component analysis (PCA) was performed based on expression of all genes from the microarray. Individual immune cell types are represented by different colors: CD19+ B cells, blue; CD8+ T cells, green; CD14+ monocytes, purple; CD4+ T cells, orange; and total PBMC, red. The method used for PBMC isolation is represented by different symbols of differing size: CPT-based procedure by large circles and Ficoll-based procedure by small circles. PC#1, principle component #1; PC#2, principle component #2
