Accelerate your exosome studies with these ready-to-use purified exosomes from the aggressive, invasive, metastatic human breast cancer cell line MDA-MB-231. Building upon ExoGlow-NTA, a proprietary dye that enables fluorescent NTA analysis of only the extracellular vesicles present in a heterogenous sample, SBI has developed a new version compatible with Particle Metrix's ZetaView instrument. The new ExoGlow-NTA Fluorescent Labeling Kit (for Particle Metrix ZetaView) provides accurate EV NTA data that excludes protein aggregates, membrane fractions, and other background particles to provide EV-specific particle size and concentration.
