Fig 3. TAT-NMR-CaM cell-penetration assay.
A, control with 400 nM CBS-MBP only and B, TAT-NMR-CaM/CBS-MBP (400 nM each) added to BHK cells; CBS-MBP was labelled (rendered as yellow) and cell nuclei (white) were stained prior to imaging with NucBlue. Cells were imaged with 40X objective at mid-point depth in cell and scale bar = 20 μm.
