Anti smad5 antibody

The Western blotting analysis was performed using standard procedures. The following primary antibodies were used in the experiments: anti-PTBP1 antibody (Cell Signaling Technology, Beverly, MA, USA), anti-PTBP2 antibody (Abcam, Cambridge, UK), anti-PTBP3 antibody (Sigma-Aldrich, St. Louis, MO, USA), anti-HNRNPK antibody (Abcam), anti-HNRNPM antibody (Sigma-Aldrich), anti-FUBP3 antibody (Abcam), anti-CPSF2 antibody (Abcam), anti-G3BP2 antibody (Atlas Antibodies), anti-TGFβ1 antibody (Proteintech Group), anti-TGFβ2 antibody (Abcam), anti-p-SMAD2 antibody (Cell Signaling Technology), anti-SMAD2 antibody (Cell Signaling Technology), anti-p-SMAD3 antibody (Cell Signaling Technology), anti-SMAD3 antibody (Cell Signaling Technology), anti-SMAD5 antibody (Abcam), anti-ID2 antibody (Abcam), anti-ZEB1 antibody (Abcam), anti-SNAI antibody (Abcam), anti-E-cadherin antibody (Proteintech Group), anti-Vimentin antibody (Cell Signaling Technology), anti-N-cadherin antibody (Cell Signaling Technology) and anti-GAPDH antibody (Sigma-Aldrich). The blots were incubated with a goat anti-rabbit or anti-mouse secondary antibody (Sigma-Aldrich) and visualized with a commercial ECL kit (Pierce, Rockford, IL).
