From: Screening for peptides targeted to IL-7Rα for molecular imaging of rheumatoid arthritis synovium
IL-7 receptor (IL-7Rα) expression detected by immunohistochemical analysis is compared to ultra-small superparamagnetic particles of iron oxide (USPIO)-P258 and USPIO-poly(ethylene glycol) (USPIO-PEG) (stained by Perls’-3,3'-diaminobenzidine (DAB)) capture in the hind limbs of mice with collagen-induced arthritis studied by magnetic resonance imaging. Histological structures were examined using Masson’s Trichrome staining. For each experimental group, the different staining methods were applied on sequential sections from the same mouse joints
