SDS-PAGE of a representative MUV sample purified by HIC with protein annotations after MALDI-TOF/TOF MS analysis. Three separate samples were analysed in total. E1 – eluate with 0.5 M (NH₄)₂SO₄, 50 mM HEPES, E2 – eluate with 50 mM HEPES, MVP – major vault protein, G3BP – galectin-3-binding protein, CypA – cyclophilin A, ni – not identified. Rectangles denote areas where large gel pieces (possibly containing multiple but very faint bands) were excised
