Transcription Factor Permeation:
B. Cupid-cMyc protein labelled with fluorescein was subjected to SDS-PAGE and observed with a blue light transilluminator.
M = Weight markers shown in Kd, S = Labelled Cupid-cMyc protein sample.
C. Labelled protein was incubated with living cells at 5 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 Cupid-cMyc protein fluorescence distributed diffusely throughout all cells.

Cupid-cMyc Protein Data
A. Purified Cupid-cMyc protein was subjected to SDS-PAGE alongside a prestained molecular marker ladder. The gel was then stained for protein with a commercial coomassie-based stain.
