Fig. 1From: Targeting mannose receptor expression on macrophages in atherosclerotic plaques of apolipoprotein E-knockout mice using 68Ga-NOTA-anti-MMR nanobody: non-invasive imaging of atherosclerotic plaquesIn vitro binding selectivity and specificity assay. In vitro binding selectivity and specificity of 68Ga-NOTA-anti-MMR Nb to MR were tested on M1- and M2a-polarized macrophages, as well as on M2a-macrophages pre-treated with a 1000-fold excess of non-labelled NOTA-anti-MMR Nb 5 min prior to the addition of 10 nM 68Ga-NOTA-anti-MMR NbBack to article page
