Optimised solution for exosome detection by flow cytometry

Biotium, a supplier and inventor of fluorescent cellular probes for life science research, has announced the release of new ExoBrite EV Membrane Staining Kits.

These kits are designed for fluorescent staining of exosomes or extracellular vesicles (EVs) with little to no background. ExoBrite EV Membrane Stains are validated for flow cytometry, but also have potential applications in super-resolution imaging or other exosome detection platforms.

Extracellular vesicles, including exosomes, are increasingly studied for their roles in cell communication, and as potential targets for diagnostic and drug delivery applications. However, reliable staining of EV membranes has been hampered by challenges of dye aggregation, and the lack of bright and specific probes. ExoBrite EV Membrane Staining Kits were developed by Biotium scientists as an optimised solution that addresses the challenges of EV detection. The stains are suitable for purified and bead-bound exosomes and can be combined with antibody staining for multi-parameter analysis.

Biotium also offers several other tools for EV detection, including antibodies specific for the exosome markers CD9, CD63, and CD81, as well as other membrane stains validated for EV detection by flow cytometry. The release of ExoBrite EV Membrane Staining Kits marks Biotium’s first product line developed specifically for EV and exosome research.

ExoBrite EV Membrane Staining Kits are available with two-colour options for the FITC or PE channels. More colour options for blue and red channels are coming soon. The standard kit will offer 500 labeling reactions while the trial size kit will offer 100 labeling reactions.
