The DMSN facilitates antigen delivery to lymph nodes. (A–C) Schematic representation of the study design. FITC-RBD or FITC-peptide (10 µg per mouse) with the DMSN (50 µg per mouse) was subcutaneously inoculated into the tail base of BALB/c mice. The same amount of FITC-RBD or FITC-peptide with PBS served as a mock control. At 12 h postincubation, inguinal LNs were isolated and monitored using the IVIS Spectrum
