A) Schematic presentation of cellular uptake of CPP‐Ub conjugates; nuclear TAMRA intensity is the measure of active cytosolic delivery of the protein cargo. B)–G) Quantified live‐cell delivery of synthetic CPP‐Ub analogues, Ub1–Ub13 at a fixed concentration of 2 μM using CLSM by nuclear masking method. Data were plotted as mean ± SEM of four independent biological experiments and statistical significance was determined by unpaired t‐test (*, P<0.1; **, P<0.01; ***, P<0.001; ****, P<0.0001; and ns, nonsignificant).
