Technology Highlight: ExoBrite™ True EV Membrane Stains

ExoBrite™ True EV Membrane Stains outperform PKH67 for high EV coverage with low aggregation in flow and fTNA.

The Best Choice for Pan-EV Staining

ExoBrite™ CTB EV Staining Kits are designed for robust staining of isolated EVs by flow cytometry or microscopy with minimal background.

Features

  • Novel lipophilic membrane dyes designed for pan-EV labeling
  • Superior alternative to common membrane dyes like PKH, DiO, DiI, DiD
  • Fewer aggregates and better detection by flow cytometry than other common dyes
  • Near-complete coverage of EVs in a sample
  • Broad compatibility with EVs isolated from different sources
