Evaluation of DB67 core region for GD2 recognition and binding. (A) The three-dimensional of DB67. DB67 was mainly composed of several stem-ring structures. (B) Black box docking position of DB67. (C) Recognition of system balance between DB67 and GD2 molecules. (D and E) Molecular docking. The C11^th, C12^th, C13^th, C32^th, C34^th, A35^th, and C36^th could form polar interaction. (F) Flow cytometry assessment of truncated DB67 for GD2 binding specificities. DB67 was truncated and truncated sequence L-DB67, R-DB67, DB67-active, and DB67 were incubated with IMR32 cells. Fluorescence signals were detected.
