Figure Lengend Snippet: Gel-shift analysis of T. neapolitana and E. coli DNA operator regions binding to cell-free synthesized T. neapolitana ArgR and T. maritima putative regulatory proteins. Lane 1—without protein; lanes 2–5 contain 12, 24, 48, and 96 nM operator DNA. His-tagged purified proteins were probed to labeled operator DNA at 37 °C for 30 min and subjected to electrophoresis on a 2% agarose gel. ArgR binding was carried out in the presence of L-arginine in both binding and running buffers.
Article Snippet: DNA concentration was determined by spectrophotometry and confirmed by comparing band intensity with a Smart Ladder reference DNA (Eurogentec, Liege, Belgium) after electrophoresis.
