Figure Lengend Snippet: Representative ITC thermograms (top panel) and corresponding integrated binding isotherms (bottom panel) for (A) WT FGF1 and (B) FLEX titrated with polymeric heparin from three independent experiments. Experiments were performed at 25 °C in Tris pH 7.4 with 100 mM NaCl. Data were fitted using a single-site binding model.
Article Snippet: Membranes were blocked in Tris-buffered saline with 0.1% (v/v) Tween 20 (TBS-T) in 5% (w/v) non-fat dried milk (pH 7.4) followed by incubation with primary anti-6His tag antibody (Bio-Rad or Cell Signalling Technologies) and secondary horse radish peroxidase-conjugated anti-mouse (ThermoFisher) antibody.
