TECHNICAL NOTE 8 ©2021 NanoTemper Technologies, Inc. South San Francisco, CA, USA. All Rights Reserved. Analysis so ware (NanoTemper Technologies). For the IMAC purifications the clarified lysates were applied to 50 μl Ni-NTA columns, equilibrated with binding (50 mM Tris-HCl pH 8.0, 300 mM NaCl, 20 mM imidazole, 0.01% (v/v) 1-thioglycerol). Next, the columns were washed with approx. 1 ml of binding buffer and bound proteins eluted with 250 μl elution buffer (50 mM Tris-HCl pH 8.0, 300 mM NaCl, 300 mM imidazole, 0.01% (v/v) 1-thioglycerol. SDS-PAGE gels were runs according to Laemli2. Samples of the lysate, clarified lysate (10 μl + 30 μl loading buffer each) and the elution fraction (20 μl + 20 μl loading buffer) were applied to the 15% acrylamide gels. The gels were stained with Page Blue protein staining solution (Thermo Scientific) following the manufacturer's instructions.
