Mice were administered 3 μg of OVA in PBS containing 30% HP-β-CyD and 10 μg of Alexa Fluor®;594-labeled K3 CpG-ODN at the base of the tail. After 24 h, the draining lymph node was collected, and the cells were stained and measured following the procedure above. The percentages of Alexa Fluor®;594+ cells of conventional dendritic cells (CD11c+ Siglec-H−), plasmacytoid dendritic cells (CD11c+ Siglec-H+) and B cells (CD19+) were analyzed by FlowJo software (Tree Star).
