NuPAGE Novex Bis-Tris gel (Life Technologies), transferred to
PVDF membrane (Millipore), blocked in 1 × TBS-Tween with 5% non-fat dry milk and incubated with corresponding primary antibody and secondary antibodies. The following antibodies were used: rabbit anti-TGM2, (1:1,000; Cat. No. HPA021019, Sigma-Aldrich, Prestige Antibodies Powered by Atlas Antibodies), Rabbit anti-CLIC3 (1:3,000; produced in house31 (
link)),
Rabbit anti-β-tubulin (1:1,000; Cat. No. sc-9104, Santa Cruz),
Mouse anti-Vinculin (1:1,000; Cat. No. V9131, Sigma-Aldrich) and
Mouse anti-αSMA (1:1,000; Cat. No. A5228, Sigma). As secondary antibodies, horseradish peroxidase-conjugated (1:10,000; Cat. No. HAF008 and HAF007, H&D systems,), IRDye 680RD (1:10,000; Cat. No. 926-68072, LI-COR) and
IRDye 800CW (1:10,000; Cat. No. 926-32213, LI-COR) were used. Images were captured with a Bio-Rad GS-800 Calibrated densitometer (Quantity-One software version 4.6.3) or a LI-COR
Odyssey CLx scanner (Image Studio software, version 5.0.21) for chemluminiscent or fluorescence western blots, respectively. Representative images from reproducible, independent experiments are shown. Uncropped scans of the western blots are reported in
