Whole-tissue BAT lysates were prepared as previously described and quantified by Direct Detect (Millipore) (23 (link)). For blotting NCoR1/2, 50 μg protein lysate was loaded per lane, with each lane representing a separate biological replicate. Ladder used was a prestained high-range multicolor protein ladder (26625; Thermo Fisher Scientific). Wet transfer to PVDF was done overnight, and primary antibodies were applied in 5% BSA overnight, all at 4 °C. Primary antibodies used were anti-SMRTe (06-891; Millipore; 1:1,000), anti-NCoR1 (5948S; Cell Signaling Technology; 1:1,000), and anti-Vinculin (V9264; Sigma; 1:5,000), with appropriate HRP-linked secondary antibodies (Cell Signaling Technology; 1:10,000) applied at room temperature for 1 h. Blots were revealed using either film or a Bio-Rad ChemiDoc.
