Total RNA profiles for human and bovine MEV and cream fractions. Total RNA contained in fluff (red) and serum (green) MEV fractions were isolated from SEC F1/S1 peaks concentrated by reverse osmosis. Cream was sampled from the first centrifugation of raw milk. RNA extracts were analysed on Agilent RNA 6000 Pico chips using an Agilent Bioanalyzer. The total MEV RNA content was related to the initial start volume of milk (ng ml^–1 milk). The peak at 25 nt is an internal standard. Abbreviations: FU, fluorescence units; nt, nucleotides; hF1, human fluff MEV; hS1, human milk serum MEV; bF1, bovine fluff MEV; bS1, bovine milk serum MEV.
