Optimised solution for exosome detection by flow cytometry

Biotium has released of new ExoBrite EV Membrane Staining Kits, 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 both for purified and bead-bound exosomes and can be combined with antibody staining for multi-parameter analysis.

“Extracellular vesicle and exosome research is a fast-growing field for life science research. Yet the current probes available for EV detection require significant troubleshooting and have varying results depending on the sample type,” says Dr Alexis Madrid (Principal Scientist at Biotium). “We wanted to give scientists the tools to streamline their EV research, and spend more time making discoveries in this exciting field”.

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.
