Fractions 40–80 min were collected, concentrated and processed for mass spectrometry‐based proteomic analysis. (A) EV markers Syntenin‐1, Flotillin‐1, CD63, CD9, CD81, Flotillin‐2, Alix and TSG101 were analysed (missing sample indicated in grey). Z ‐score transformation of intensities were plotted. (B) Targeted mass spectrometry analysed the presence of PSMA (FOLH1) in patient samples. The z ‐score transformation of intensities was plotted with the AF4‐MALS‐FLD peak area. (C) Blood plasma samples of healthy controls ( n = 7) and HER2 amplified breast cancer patients ( n = 10) were labelled with PE‐conjugated anti‐HER2 antibodies. (D) Blood plasma samples of healthy controls ( n = 6) and breast cancer patients ( n = 8) were labelled with PE‐conjugated anti‐EpCAM antibodies. The area under the curve values were normalised for the mean value in the healthy control group.

    Article Snippet: Detection was performed by an ultraviolet (UV) detector at 280 nm (Shimadzu), a multi‐angle light scattering (MALS) detector DAWN HELEOS‐II using a laser at 658 nm (Wyatt Technology) and a fluorescence detector (FLD) with an excitation at 488 nm, emission at 578 nm and a gain of 16 (Agilent Technologies) (Geeurickx et al. ).

    (A) Domain structure of S. pombe HULC subunits. CC: coiled coil; RING: really interesting new gene domain. RBD: Rad6-binding domain, IDR: intrinsically disordered region, UBC: Ubiquitin C E2 ligase domain (B) SDS PAGE gel of size exclusion peak fraction of HULC and western blot against T7-tagged Brl1, Shf1 and Rhp6 after StrepII-tag pull-down of HULC. (C) Mass photometry size distribution of affinity-purified HULC. (D) Size exclusion coupled with multi-angle light scattering (MALS) showing UV chromatogram overlaid with molecular mass determination for HULC peak. (E) Sedimentation velocity c(S) distribution of HULC after size exclusion chromatography (see fit in Fig. S2). (F) Spot assay of indicated S. pombe strains on yeast extract agar (YE). (G) Quantification of red colony frequencies for the mutant strains used in (F). All solution experiments were in 20 mM HEPES pH 7.5, 150 mM KCL, 2 mM MgCl 2 .
