Fig. 2From: MRI detection of endothelial cell inflammation using targeted superparamagnetic particles of iron oxide (SPIO)Cell phantom preparation. Six samples were prepared. They are the activated cells stimulated by TNF-α of different concentration (1 ng/mL, 10 and 100 ng/mL). The controls are activated cells with biotinylated IgG antibodies and microbeads as negative control, unactivated cells as negative control, and streptavidin microbeadsBack to article page
