Protein and DNA were mixed in binding buffer (0.5 M Tris-HCl pH 8.0, 250 mM NaCl, 0.1 M EDTA, 0.1 mM dithiothreitol, 0.05% Brij58, 10 μg/mL BSA, and 5% glycerol) and incubated at room temperature for 30 min. The high concentration of Tris was used to prevent pH changes upon subsequent addition of urate dissolved in 0.4 M NaOH.
The principal method used to prevent crashes associated with routine changes in signal indications is employment of a traffic signal change interval — a brief yellow and all-red period that follows the green indication.
