Exosome Standards

Exosomes are small endosome derived lipid nanoparticles (50-120 nm) actively secreted by exocytosis in most living cells. Lyophilization is the ideal technique for preserving the long-term stability of exosomes at 4°C. Lyophilized exosomes can be used as the control standards for multiple applications including FACS, WB, ELISA and as calibration standards for quantitation of exosome-derived markers from biological samples. ExoStd™ lyophilized exosome standards are standardized positive controls for immunocapture performance evaluation. Biovision provides highly purified Lyophilized Exosome Standards from Human Plasma, Serum, Urine and Saliva pool of healthy donors and from different cell lines.

Lyophilized Exosome Standards are offered in two sizes including 30 μg and 100 μg and sold in packages of 2, 4 or 6 vials.
  • Quantity per vial: 100 µg (number of particles in 100 µg: > 1x10¹⁰)
  • Quantity per vial: 30 µg (number of particles in 30 µg: > 1x10⁸)

1. ExoStd™ Lyophilized Exosome Standards from human biological fluids:
