Abstract
A novel complementation system with short peptideinsertedRenilla luciferase PIRluc and splitRNA probes was constructed for noninvasive RNA detection The RNA binding peptides HIV1 Rev and BIV Tat were used as inserted peptides They display induced fit conformational changes upon binding to specific RNAs and trigger complementation or discomplementation of Rluc SplitRNA probes were designed to reform the peptide binding site upon hybridization with arbitrarily selected target RNA This set of recombinant protein and splitRNA probes enabled a high degree of sensitivity in RNA detection In this study we show that the Rluc system is comparable to Fluc but that its detection limit for arbitrarily selected RNA at least 100 pM exceeds that of Fluc by approximately two orders of magnitude
