Double sense: A novel multiple-catalytic DNA sensing method utilises a chimeric probe that targets both the DNA and reporter mRNA. The technique uses just probe, RNase H, luciferase mRNA and wheat germ extract. With its four discrete catalytic processes including cycling probe technology, this method shows relatively high sensitivity and specificity despite requiring neither labelling nor nucleic acid amplification.
