<i>In vitro</i> gene silencing.

<p>Silencing of a luciferase reporter protein in HEK293(A), PC-3(B), Mat(C) cells were conducted with the liposome/siRNA complexes (Ara-DiC12MA, Ara-DiC14MA, Ara-DiC16MA, Ara-DiC18MA). The mean luciferase activity was represented by relative light unit and was calculated from three different measurements. Statistical differences from the Lipo2000 are labelled * P < 0.05, ** P < 0.005 and *** P< 0.001.</p>
