TCEs were separated on 10% SDS-PAGE gels, transferred to nitrocellulose membranes, incubated first with the primary antibodies against proteins or protein phosphor-isoforms of interest (Supplemental Table S1) and then with IRDye 680RD secondary antibodies (cat. no. 92668070, LI-COR, Lincoln, NE). Immunoblots were detected using the LI-COR’s Odyssey CLx imaging system. Membranes were stripped and re-incubated with antibodies against β-actin, which served as a loading control.
