Finally, you can take full advantage of the power of flow-based methods for analyzing extracellular vesicles (EVs) with SBI’s exclusive ExoFlow-ONE Gemstone dyes. By specifically labeling internal EV components with one of these proprietary, high quantum efficiency dyes, you can achieve near single-vesicle resolution* for more powerful flow cytometry and FACS studies, and uncover greater insights into EV biology. The ExoFlow-ONE Topaz Blue Gemstone Dye Kit comes with enough labeling reagents for 25 reactions. Each kit also includes 1.5 mL of silica bead size standards (110 nm – 1300 nm), two of which are fluorescent. The silica beads, sourced from Apogee Flow Systems, are specifically designed to produce a refractive index and light scattering patterns similar to biological particles, enabling more accurate estimation of EV particle size.
