Characterization and stability analysis of CP-bi-apt

(A and B) The analysis of CP-bi-apt with/without the treatment of T4 DNA ligase under (A) 2% agarose gel electrophoresis and (B) 7 M-urea-containing polyacrylamide gel electrophoresis. (C and D) The stability of CP-bi-apt with or without the treatment of T4 DNA ligase after incubation in (C) nuclease I/III or (D) 50% FBS at different time points (0 h, 6 h, 12 h, and 24 h) is shown. (E) The expression of PD-L1 in HeLa, SMMC-7721, and QSG-7701 cells.
