SEC-purified MCF-7-derived EVs were stained with ExoBrite™ 640/660 CD9 Flow Antibody (left). Specific staining was seen, compared with the same antibody in buffer (right). Exosomes were detected on a CytoFLEX LX flow cytometer in the R660 (APC) channel.
SEC-purified MCF-7-derived EVs were stained with ExoBrite™ 650/665 CD9 Flow Antibody (left). Specific staining was seen, compared with the same antibody in buffer (right). Exosomes were detected on a CytoFLEX LX flow cytometer in the R660 (APC) channel.
SEC-purified HeLa-derived EVs were stained first with ExoBrite™ 560/585 CD9 in 100 uL, followed by 1X ExoBrite™ 650/665 Annexin EV Stain. EVs were detected on a CytoFLEX LX flow cytometer in the PE and APC channels. When we gated on ExoBrite™ 650/665 Annexin-positive particles, ~50% were also positive for CD9.
SEC-purified MCF-7-derived EVs were stained with ExoBrite™ APC CD9 Flow Antibody (left). Specific staining was seen, compared with the same antibody in buffer (right). Exosomes were detected on a CytoFLEX LX flow cytometer in the R660 (APC) channel.
EVs were isolated from MCF-7 cell supernatant with CD9 affinity beads. The bead-bound EVs were stained with ExoBrite™ CD9 490/515 Flow Antibody (green) or ExoBrite™ 490/515 IgG1 Isotype Control Flow Antibody (gray), then analyzed by flow cytometry in the FITC channel.

Validated Antibody for Optimal Detection of EV Marker CD9

ExoBrite™ CD9 Flow Antibody is a monoclonal IgG1, kappa antibody validated by Biotium for the optimal detection of CD9, a key extracellular vesicle (EV) marker, by flow cytometry. Designed for use with both purified and bead-bound EVs, this antibody ensures bright signal, low background, and exceptional signal-to-noise performance.

Now available with an updated buffer formulation for improved staining specificity, ExoBrite™ CD9 Flow Antibody is supplied in six colour options (Pacific Blue™, FITC, PE, APC, R-PE, and APC conjugates) to support flexible multi-parameter EV analysis.

CD9, along with CD63 and CD81, belongs to the tetraspanin family, which is broadly expressed across many cell types. Its widespread presence on EVs makes CD9 a reliable biomarker for EV detection and characterisation.

Key Features

  • Optimal detection of EV marker CD9 by flow cytometry
  • Bright fluorescence, low background
  • Validated for purified and bead-bound EVs
  • Six colour options for flexible panel design
  • Updated buffer formulation for improved signal-to-noise

Notes: Biotium products are available only in Singapore and Thailand.

 

Detect EVs with confidence using ExoBrite™ CD9 Flow Antibody – validated for purified and bead-bound vesicles.
