Abstract: Synthesis of Ar@C 60 is described, using a route in which high-pressure argon filling of an open-fullerene and photochemical desulfinylation are the key steps for % encapsulation of the noble gas.

Abstract: The large size of biological molecules such as proteins and oligonucleotides makes them inherently problematic to analyse and quantify directly by mass spectrometry. For these molecules, electrospray ionisation produces multiply charged species and associated alkali metal adducts which can reduce sensitivity and complicate quantification. Whereas time-of-flight mass analysers, often coupled to matrix-assisted laser desorption/ionisation, can have insufficient mass resolution to resolve these large molecules in the higher m/z range. This has led to the development of cleavable small molecule mass tag approaches for the indirect analysis of biomolecules such as proteins and oligonucleotides. Existing methodologies require the design and synthesis of a cleavable linker to join the biomolecule and the mass tag. Here, an alternative approach to small molecule mass tags is presented, which exploits the properties of the RNA molecule to afford self-reporting probes which can be easily synthesised using automated phosphoramidite chemistry. The sugar-phosphate backbone of RNA was used as a built-in enzyme cleavable linker and through the use of RNase digestion of bromine labelled oligonucleotides the observation of a range of small molecule mass tags by mass spectrometry is demonstrated. This study provides a proof-of-concept that RNase digestion can be used to produce labelled small molecule mass tags from oligonucleotide probes, thus eliminating the need for custom design and synthesis of a cleavable linker.

Abstract: Hybridisation assays, which are commonly used to analyse oligonucleotides such as siRNAs and miRNAs, often employ detection probes with fluorescent tags. The signal emitted by a fluorescent tag covers a broad range of wavelengths and this limits the multiplexing potential due to overlapping signals. A novel method of indirect oligonucleotide analysis has been developed which combines a hybridisation assay with cleavable small molecule mass tags using HPLC-ESI MS detection. A self-reporting detection probe has been designed which incorporates a DNA/RNA chimeric oligonucleotide sequence in the reporter region, which generates small nucleotide products upon RNase cleavage of the ribose-phosphate backbone. These small nucleotides can then serve as mass tags for the indirect detection of oligonucleotide analytes. The narrow mass range covered by a small molecule mass tag combined with the wide range of possible mass tags provides a high degree of multiplexing potential. This approach has been demonstrated for the analysis of a synthetic miRNA.
