The C-CPE-Strep-Tactin Chromeothrough the visualization ofalong 488 complicated CPE-CLDN binding. The C-CPE-Strep-Tactin Chromeo 488 complicated was detected along CPE-CLDN binding. The C-CPE-Strep-Tactin Chromeo 488 complex was among adjacent cell membranes of native and transfected cell lines at cell ell junction detected along cell membranes native and transfected cell lines at cell ell junction involving adjacent cell membranes of of native and transfected cell lines at cell ell junction between adjacent cells (Figure 3). cells (Figure cells (Figure three).3).Figure three.

Uncoupled coupled AuNPs showed a broad distribution in the cell surface, while C-CPE AuNPs were AuNPs showed a broad distribution in the cell surface, though C-CPE AuNPs have been identified discovered mainly positioned in close distance to cell ell borders. Whereas the presence of primarily situated in close distance to cell ell borders. Whereas the presence of AuNPs and AuNPs and C-CPE-AuNPs on microvilli might indicate nonspecific surface binding, the C-CPE-AuNPs on microvilli may possibly indicate nonspecific surface binding, the internalization internalization of AuNPs was clearly visible by SEM in some areas (see Supplementary of AuNPs was clearly visible by SEM in some areas (see Supplementary File S1). file S1).Figure 4.
