Cupid-p53-A Peptide Data:
Cell permeating Cupid p53 peptide AA. Purified Cupid-p53-A peptide was subjected to SDS-PAGE alongside a prestained molecular marker ladder. The gel was then stained for protein with a commercial coomassie-based stain.

C. Labelled peptide was incubated with living cells at 10 micromolar for 60 minutes before exchanging the media and washing the cells. Cells were imaged using a fluorescence microscope with filter sets for Fluorescein (Upper Panel) or phase contrast (Lower Panel). Fluorescent images of treated cells are taken at a setting where the background (autofluorescence) of the untreated cells is at the threshold of detection. We observe the peptide fluorescence distributed diffusely throughout all cells.
