Cellular uptake of ssCpG and tetraCpG in mock-transfected or MSR1-transfected HEK-Blue hTLR9 cells in the presence of mouse IgG1 isotype control or hMSR1 antibody. Each Alexa Fluor 488-labeled DNA sample was added to cells at a final concentration of 2 μg/mL. The results are expressed as means + SEM of four independent experiments.
