RNA cleavages by many ribonucleases generate RNA molecules that contain a 2′,3′-cyclic phosphate (cP) at their 3′-termini, and many cP-containing RNAs (cP-RNAs) are expressed as functional molecules in cells and tissues. 5′-tRNA half molecules are representative examples of functional cP-RNAs, playing important roles in various biological processes. We here show in vitro production of cP-containing 5′-tRNA half molecules that is able to prepare abundant synthetic cP-RNAs enough for functional analyses. Furthermore, we report a multiplex TaqMan RT-qPCR method which can simultaneously quantify multiple cP-containing 5′-tRNA half species. The method enabled us to efficiently quantify 5′-tRNA halves using samples with limited amounts, such as human plasma samples, revealing drastic enhancement of 5′-tRNA half levels at approximately 1000-fold in patients infected with Mycobacterium tuberculosis. These in vitro production and multiplex quantification methods can be applied to any cP-RNAs, and they provide cost-effective, in-house techniques to accelerate expressional and functional characterizations of 5′-tRNA halves and other cP-RNAs.
