Local retention and diffusion kinetics of model antigen Cy7-OVA in ICR mice injected via various routes. (A) Representative in vivo images of three mice injected with the same amount of Cy7-OVA (fluorescence intensity of 1440 in Eppendorf Tube^®) by intradermal (ID), intramuscular (IM), subcutaneous (SC) and intraperitoneal (IP) routes. (B) Relative fluorescence radiance of Cy7-OVA via various inoculation routes shown as fluorescent region area multiplied by average fluorescence intensity. (C) Retention and diffusion kinetics of model antigen Cy7-OVA at injection sites shown as the fluorescent regional area around injection sites.
