Exo-FITC Exosome FACS stain

Product Description

Visualize bead-immobilized exosomes with this proprietary, reversible FITC-based stain

Optimized for our Exo-Flow Capture Kits and available only from SBI, Exo-FITC is a proprietary reversible fluorescent stain for visualizing exosomes. Exo-FITC is comprised of the commonly used fluorophore fluorescein isothiocyanate (FITC) conjugated to a protein that recognizes post-translational modifications on exosomal surface proteins, enabling general staining of exosomes.

However, the feature that really makes Exo-FITC stand out as an ideal reagent for FACS-based isolation of exosomes is its reversibility—after staining with Exo-FITC and flow-sorting by FITC-positive gating (Exo-FITC’s excitation and emission wavelengths are 494 nm and 518 nm, respectively), Exo-FITC can be removed from exosomes through the simple addition of Exosome Elution Buffer, which simultaneously elutes exosomes from the Exo-Flow magnetic beads and removes bound Exo-FITC.

Note that we also offer reversible Exo-APC as an alternative stain to Exo-FITC.

Use Exo-APC with any of SBI's Exo-Flow Capture Kits
