Track and Quantitate Exosomes

Exosomes are small membrane vesicles secreted by most cell types in vivo and in vitro. Exosomes are found in cell culture media, blood, urine, amniotic fluid, malignant ascite fluids and contain distinct subsets of microRNAs and proteins depending upon the tissue from which they are secreted. SBI's ExoELISA kits are designed for fast and quantitative analysis of three well-characterized exosomal protein markers: CD63, CD9, CD81 or Hsp70.
The exosome antibody kits (cat#s EXOABxxx) allow for the confirmation of exosome recoveries and the ExoELISA kit enables the specific quantitation of CD63, CD9 or CD81 positive exosome microvesicles. The exosome antibody and ExoELISA kits are fully compatible with exosomes isolated by SBI's ExoQuick or ExoQuick-TC as well as ultracentrifugation methods.
