SARS-CoV-2 (IMAGE) Naval Research Laboratory Caption Image: Here we see the QD608-RBD binds ACE2 and induces endocytosis. In this figure, the top panel shows ACE2-GFP (yellow) expressing cells binding and internalizing QD608-RBD (magenta). In the bottom panel, an inhibitor is added to prevent binding of QD608-RBD to ACE2-GFP, and the presence of ACE2-GFP on the cell surface is strong with little to no QD608-RBD visible. Scientists at the U.S. Naval Research Laboratory and National Center for Advancing Translational Sciences (NCATS), published their findings in ACS Nano, a monthly peer-reviewed scientific journal, on their collaboration to develop SARS-CoV-2 nanoparticle probes that are used to study fundamental interactions between SARS-CoV-2 Spike proteins and human cells.
