Radiochemical purity and stability of radioiodine labeled EVs. (A) Instant thin layer chromatography (ITLC) showed good radiochemical purity after radioiodine labeling. Radiochemical purity of I-131-Cal62-EVs and I-131-NK-EVs after purification were 98.9 ± 1.8% (n = 3) and 98.6 ± 0.9% (n = 3). (B) Stability of I-131-Cal62-EVs was examined in 20% fetal bovine serum (n = 3). The level of stability was analyzed by ITLC. Data are presented as mean ± standard deviation.
