For the selective capture and flow sorting (FACS) of exosome subpopulations based on the presence of CD63, which is a general exosome marker. The CD63 Exo-Flow Capture Kit has all the reagents you need to purify exosomes using FACS—magnetic streptavidin beads, CD63-biotin capture antibody, wash and elution buffers, and reversible Exo-FITC stain (Cat.# EXOFLOW800A-1)—you supply the FACS and the optional magnetic stand (Cat.# EXOFLOW700A-1). Our well-validated CD63-biotin antibody and high-quality kit components ensure reliable, reproducible exosome purification based on the presence of CD63 on the exosome surface. And with our larger-than-typical bead size (9.1 μm diameter) exosome capture is highly efficient, assisting with recovery of rare exosome populations.
