Methods and kits for isolating tumour-derived exosomes by immunocapture with an anti CA-IX antibody, quantifying tumour-related nucleic acid sequences from the isolated exosomes and determining in vitro the presence of a tumour in a subject are provided.

The invention provides a series of steps that prepare nucleic acids (RNA and/or DNA) isolated from extracellular vesicles for sequencing. This enables a wide diversity of RNAs and/or DNAs, to be efficiently detected. These can then be used to identify various attributes such as gene expression, alternative splicing, and the detection of both somatic and germline mutations including single nucleotide variants (SNV) and structural variations (insertions/deletions, fusions, inversions).

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.
