Fig. 6From: The effect of injection speed and serial injection on propidium iodide entry into cultured HeLa and primary neonatal fibroblast cells using lance array nanoinjectionInjection speed box plot. The two left-most box plots were the result of the slower stepper motor (Rohs) whereas the three right-most box plots were the result of the faster stepper motor (AA). Statistically significant relationships are noted with an asteriskBack to article page
