Figure S2 from Exosomal Thomsen–Friedenreich Glycoantigen: A New Liquid Biopsy Biomarker for Lung and Breast Cancer Diagnoses

Supplementary Figure S2. SPR assay demonstrated exosomes carry TF-Ag-α. Exosomes were isolated from cancer patient serum samples using both total exosome isolation kit (from serum) (ThermoFisher) and exoRNeasy midi kit (Qiagen). Significantly higher levels of TF-Ag-α were observed in exosome samples isolated using both kits than the exosome-depleted serum samples. The exosome concentration was 3.29x10^11 exosomes/mL.
