CXCR3 expression in normal peripheral blood lymphocytes.

(A) Flow cytometric detection of CXCR3 in peripheral blood using the FITC-conjugated monoclonal antibody, 49801.111. Cytograms represent staining of cells within the lymphocyte gating for CD5 and CXCR3 (right panel) in comparison with an IgG1 isotype control antibody (middle panel). (B) CXCR3 expression in peripheral blood B cells as determined by CD19/forward scatter gating in a 3-color staining profile (CD19/CD5/CXCR3). Numbers correspond to percentage of total gated B cells in each quadrant.
