FIG. 5.
Polyacrylamide gel electrophoresis analysis of screened peptides used (a-1) HCT-8 (H) as target cells and CRSC (C) as control cells, and (a-2) presented the OD values analysis with several PAGE results (n = 5), indicating that the amount of PCR product was observed to increase and become saturated from H1st to H6th; (b-1) CRSC as target cells and HCT-8 as control cells,28 and (b-2) presented the OD values analysis with several PAGE results (n = 5), indicating that the amount of PCR product was observed to increase and become saturated from C1st to C6th. P: positive control using phage library. N: negative control using ddH2O. L: 50-bp ladders. Lanes H1st to H6th and C1st to C6th represent the first to the sixth round of the selection, respectively.
