Study summary Full title NA All authors NA Journal Abstract NA (show more...)NA (hide) EV-METRIC 56% (57th percentile of all experiments on the same sample type) Reported Not reported Not applicable EV-enriched proteins Protein analysis: analysis of three or more EV-enriched proteins non EV-enriched protein Protein analysis: assessment of a non-EV-enriched protein qualitative and quantitative analysis Particle analysis: implementation of both qualitative and quantitative methods. For the quantitative method, the reporting of measured EV concentration is expected. electron microscopy images Particle analysis: inclusion of a widefield and close-up electron microscopy image density gradient Separation method: density gradient, at least as validation of results attributed to EVs EV density Separation method: reporting of obtained EV density ultracentrifugation specifics Separation method: reporting of g-forces, duration and rotor type of ultracentrifugation steps antibody specifics Protein analysis: antibody clone/reference number and dilution lysate preparation Protein analysis: lysis buffer composition Study data Sample type heart tissue Sample origin Control condition Focus vesicles extracellular vesicle Separation protocol Separation protocol Gives a short, non-chronological overview of the different steps of the separation protocol. dUC = (Differential) (ultra)centrifugation DG = density gradient UF = ultrafiltration SEC = size-exclusion chromatography IAF = immuno-affinity capture (Differential) (ultra)centrifugation Protein markers EV: Alix/ CD9/ CD63/ CD81/ TSG101 non-EV: Calreticulin/ Albumin/ fga/ hba Proteomics yes Show all info Study aim Function/Identification of content (omics approaches) Sample Species Mus musculus Sample Type heart tissue Separation Method (Differential) (ultra)centrifugation dUC: centrifugation steps Below or equal to 800 g Between 800 g and 10,000 g Between 10,000 g and 50,000 g Between 100,000 g and 150,000 g Pelleting performed Yes Pelleting: rotor type TLA-100 Pelleting: speed (g) 100000 Wash: volume per pellet (ml) 1 Wash: time (min) 60 Wash: Rotor Type TLA-100 Wash: speed (g) 100000 Characterization: Protein analysis Protein Concentration Method microBCA Protein Yield (µg) total yield (from tissue starting sample, intact heart) Western Blot Antibody details provided?
