Promoter Activity of the <i>mNaip</i> LTRs

Abstract

<p>The ORR1E LTRs for each copy were cloned into a modified pGL3B vector and tested for luciferase activity in the MS1 cell line. pGL3B and pGL3P, containing a SV40 promoter, were used as negative and positive controls, respectively. Luciferase activity was normalized relative to the cotransfected <i>Renilla</i> luciferase control and then to pGL3B to demonstrate fold activation. Each bar represents the mean of at least four independent transfections ± SEM.</p
