Fig. 2From: Targeting the 4-1BB costimulatory molecule through single chain antibodies promotes the human T-cell responseThe purity of CD3+primary T cells isolated from PBMCs using MACS. The isolated cells were stained with anti-CD3 conjugated to FITC and isotype control antibody and analyzed via flow cytometry. The histograms show the isotype-controlled cells (left) and anti-CD3 stained T cells (right) of the enriched fraction. Results are representative of three independent experimentsBack to article page
