Cupid Control Peptide


Cell permeating Cupid Control peptide

Cell Permeating Cupid PKI Peptide

 

B. Cupid Control peptide labelled with fluorescein was subjected to SDS-PAGE and observed with a blue light transilluminator.

S = Labelled Cupid Control peptide sample.

 

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.

 

Comment: Whilst the Control Peptide has not been observed to have biological effects in doses up to 20 micro molar, Cell-Permeating peptides may be expected to influence certain cell processes through their protein nature. For example those which involve protein recycling.
