Analysis of FBS by SDS-PAGE and CD63 content by western blot

Panel A: Analysis of FBS by SDS-PAGE: Equal masses (10 µg) of FBS proteins were analyzed by SDS-PAGE. MW: Molecular weight marker. Our Exosome Depleted FBS looks very similar to the Source FBS used in production, whereas the competitor’s product shows protein band smearing. Panel B: CD63 Content by Western Blot Analysis: Exosomes were precipitated from FBS samples, run by SDS-PAGE, and probed by western blotting for CD63. MW: molecular weight marker. Compared to all other FBS samples tested, our Exosome Depleted FBS shows no observable CD63, indicating excellent exosome depletion.
