Evaluation of exosome proteins by on-bead flow cytometry
网页2022年5月22日 · On-bead flow cytometry standardized for use with conventional cytometers is a useful method for protein detection and quantitation in exosomes isolated from supernatants of cell lines or plasma of patients with cancer.
Flow Cytometric Analysis of Extracellular Vesicles - PMC
网页An early example of this approach demonstrated that 30–100 nm exosomes could be isolated from cell culture supernatants and characterized by flow cytometry, after binding the exosomes to latex beads . Shown here is a method for using streptavidin-coated beads to capture biotinylated antibodies, prior to washing the beads (to remove unbound ...
Labeling Extracellular Vesicles for Nanoscale Flow Cytometry
网页2017年5月12日 · Particle size distribution of exosomes and microvesicles determined by transmission electron microscopy, flow cytometry, nanoparticle tracking analysis, and resistive pulse sensing.
A comprehensive review on recent advances in exosome isolation …
网页Flow cytometry (FCM) Exosome subgroups can be semi-quantitatively measured using the bead-based flow cytometry method described in several publications by looking for membrane biomarkers on their surface [, , ]. In brief, exosomes are bound to aldehyde/sulfate-latex beads using a 15-minute incubation period with continuous rotation.
Evaluation of Exosome Proteins by on-Bead Flow Cytometry
网页Quantification of the molecular cargo exosomes carry by on-bead flow cytometry is needed for defining their role in information transfer and in human disease.
