PKH26 Exosome Labeling Kit

Exosomes are a class of vesicle-like structures with a diameter of about 30-150 nm, which are released into the extracellular environment by cells through exocytosis. They are found in the body fluids of almost all living organisms, including blood, urine, saliva, milk, and cell supernatants cultured in vitro. Exosomes are important tools for cell-to-cell communication, which can carry and deliver a variety of biomolecules such as proteins, lipids, RNA, and DNA, thus playing an important role in regulating immune responses, promoting tissue repair, and transmitting genetic information.

PKH26 Exosome Labeling Kit is a kit that labels and traces exosomes through the PKH26 fluorescent probe. PKH26 can bind to lipid regions on exosome membranes and emit red fluorescence signals, thereby tracking exosomes in vitro and in vivo. This kit is optimized for better labeling. At the same time, this kit provides a labeling stop solution that can terminate PKH26 labeling. The PKH26-labeled exosomes can be used for subsequent cell experiments without purification.
