The invention provides a method for detecting the presence of a target nucleic acid analyte, for example a pathogen or virus nucleic acid, in a sample using oligonucleotide probe-functionalised nanoparticles, where hybridisation of at least three different oligonucleotide probes to at least three different target sequences in the target analyte causes agglomeration of the nanoparticles and a visible colour change. The invention also provides a population of such oligonucleotide probe-functionalised nanoparticles and a related kit for detection of a target nucleic acid analyte.

The invention relates to compositions and methods for isolating extracellular vesicles (EVs) from a biological fluid sample. The compositions and methods of the invention are based on the combination of a polycation with an extracellular matrix forming polymer. Extracellular vesicles (EVs) are isolated from biological fluids such as blood, serum, plasma, saliva, urine or cerebrospinal fluid, or from the conditioned medium of a cell culture, such as an adult stem cell culture. The use of the isolation methods and compositions of the invention results in a higher EVs recovery, enrichment in exosomes, simplicity, cost-effectiveness, and in the isolation of EVs that retain their biological activities in vitro.

The present invention relates to a method for analysis of methylation of ribonucleic acid (RNA) comprising the steps: (i) contacting RNA with one or more antibodies which binds to methylated site(s) of RNA; wherein the methylated site(s) comprise at least one ribonucleotide base modified by one or more methyl groups; (ii) photo-crosslinking the one or more antibodies to crosslink individual antibodies to the RNA molecule(s) to form RNA-antibody conjugates; (iii) immunoprecipitating to separate the RNA-antibody conjugates; (iv) treating the RNA-antibody conjugates with at least one exonuclease; (v) removing the crosslinked antibodies from the RNA-antibody conjugates to release RNA; and (vi) analysing the released RNA.
