Fig. 4

Comparison of the best single NLS variant, Bxb1-NPLC, and Bxb1–NLS variants containing two or three NLS sequences. The bars represent the average normalized stable integration efficiencies (nSIE) with error bars representing the standard deviation of three independent experiments (except NPLC, n = 6; NPLCx2, n = 9).(**) p < 0.01
