ARF6 and small cell lung carcinoma: As shown in Figure 2D, DLL3 mRNA expression in Exo captured using CD63/CD81/CD9 antibodies was significantly higher in SCLC patients compared to HDs, whereas MV captured using ARF6/Annexin A1 antibodies and tEV captured using DLL3/EpCAM/ROR1 antibodies showed no significant differences.
