Fig. 5. Fold increase in luminescence as a function of (a) the net charge and (b) the number of arginines of the CPPs in the LB2–PNA705 conjugates compared to a buffer blank induced by the conversion of Beetle luciferin into oxyluciferin by expressed luciferase via splicing redirection in HeLa pLuc705 cells at 5 μM conjugate concentration. The dots represent the data points and the line represents the average.
