Fig. 4From: Intracellular lipophilic network transformation induced by protease-specific endocytosis of fluorescent Au nanoclustersCo-localization analysis between MT1-MMP and bPAuNC or pPAuNC at a single-cell level. The fluorescence intensity profiles were quantified along a line in the image of a MCF7 and b MDA-MB-231 cells incubated with bPAuNC or pPAuNC (red) and co-stained with MT1-MMP antibody (green)Back to article page
