Human cells were imaged on a confocal microscope with Akt1 labeled green, yleaf labeled pink, and the cell nuclei labeled blue. One set of cells had the healthy version of Akt1 (WT, top) and the other cancer-causing version (E17K, bottom). The yleaf targeted peptide only finds its target and remains in the cancerous cell line. The zoomed view shows the green Akt1 colocalized with the pink peptide in the cytoplasm of the cancerous cells.
