We studied the relationship between insertion of the last sense codon (i.e., the codon preceding the stop codon) and the efficiency of gene expression. We inserted 64 kinds of last sense codon at the 5’ end of the stop codon of the green fluorescen

Enzymes fixed on the electrode of biosensor are gradually inactivated and the electrode is discarded after using several times. In order to prepare the stable biosensor, we try to use a stable enzyme from extreme thermophilic bacteria, Thermus thermo

2-Azidodeoxyadenosine ( 7 ) was conveniently synthesized from deoxyguanosine ( 2 ) by use of a combined reagent of TMSN 3 –BuONO. The structure of the tautomer of the azido derivative was determined by 1 H NMR. Reaction of 7 with i Pr 2 NP(OEt) 2 g

We have shown previously that the 5′-capped short phosphodiester RNA fragments, Cap decoy, (Gm 12 nt) are potent inhibitors of influenza virus RNA polymerase gene expression. Here we investigate the modified capped RNA derivative containing phospho
