Supplemental movies for "<i>Development of a novel alpha7-nicotinic acetylcholine receptor-selective cell-penetrating peptide for intracellular cargo transport.</i><i>"</i>

Supplement Video 1: 3D movie animation of α-btx-AF647-labeled N2a cells transfected with α7 nAChR and NACHO DNA, showing binding of α-btx-AF647 to the plasma membrane of cells. Note that α-btx-AF647 fluorescence is not found in the interior of the cells. Detailed information can be found in Weber et al., 2025 preprint https://doi.org/10.1101/2025.08.08.669423. Supplement Video 2: 3D movie animation of ARA-FITC-labeled α7 nAChR expressing N2a cells. Strong ARA-FITC fluorescence can be inside the cells. Detailed information can be found in Weber et al., 2025 preprint https://doi.org/10.1101/2025.08.08.669423.
