Overview:
See EVs better with reagents specifically optimized for labeling

’s new generation of extracellular vesicle (EV) labeling reagents take your EV visualization to new levels of clarity, with low background and high selectivity. Unlike general-purpose labeling reagents that are not optimized for EVs and suffer from high levels of background signal, ExoGlow

lity to track and localize EVs by specifically and covalently labeling internal EV proteins with a proprietary red fluorescent dye that delivers very low levels of background signal. The result is unmatched EV imaging for more accurate studies (see below for our full range of next generation ExoGlow reagents).

Supporting Data:

Imaging EVs with a new level of clarity



Figure 1. ExoGlow-Protein enables clear visualization of labeled EVs being internalized by target cells.
We labeled HEK293T EVs with ExoGlow-Protein and followed uptake by HEK293T cells. The punctate fluorescence signal shows internalization of labeled EVs by the target cells.


Figure 2. Punctate staining pattern is EV-specific
. The punctate staining pattern seen in Figure 1 and Panel A is due to ExoGlow-Protein-labeled EVs. When ExoGlow-Protein is added directly to target HEK203T cells (Panel B), only diffuse, non-specific staining is seen.


Figure 3. ExoGlow-Protein signal is stable for up to at least 7 days after admi
