From: GFP-complementation assay to detect functional CPP and protein delivery into living cells
Split-complementation Endocytotic Escape (SEE): visualizing CPP functional uptake.
Live-cell functional uptake is detected when a CPP-protein fused to S11-peptide penetrates the cell membrane to complement cytosolic GFP1-10 protein, forming a functional GFP fluorophore.
