Immuno-blot analyses monitoring SA competition of 4AzSA crosslinking to recombinant cSABPs identified by the 4AzSA/immuno-selection screen. Photo-activated crosslinking of 50 ng/μl of the indicated recombinant purified proteins: (A) TRX-m1, (B) TPPII, (C) SHM4, (D) LOX2, and (E) ACX4 to 4AzSA (50 μM) in the absence or presence of increasing amounts of SA was detected by immuno-blotting using an α-SA antibody. Reactions without 4AzSA served as controls. Note that controls with 4AzSA but without photo-activation were previously shown to give similar results (Tian et al., 2012). Proteins stained with Coomassie brilliant blue (CBB) served as the loading control.
