Brainstorming and future projects

Thrombin-aptamer experiments

Questions / procedures

  • what percent gel? 10% to 20% polyacrylamide gels, no SDS (but would make for a good control)
  • what incubation conditions?
  • how much protein and DNA? protein at 1 μM, DNA at 2 μM
  • Coomassie stain

Experiments

0---no bandsno bands
1--+slow band (nanotube)no bands
2-+-fast band (aptamer)no bands
3-++slow band (aptamer-nanotube), traces of fast band (aptamer)no bands
4+--no bandsfast band (thrombin)
5+-+slow band (nanotube)fast band (thrombin)
6++-medium band (aptamer-thrombin), fast band (aptamer)medium band (aptamer-thrombin), traces of fast band (thrombin)
7+++very slow band (thrombin-aptamer-nanotube), slow band (aptamer-nantotube), traces of fast band (aptamer)very slow band (thrombin-aptamer-nanotube), medium band (aptamer-thrombin), traces of fast band (thrombin)

Buffers

  • Macaya's and Bock's selection buffer: 20 mM Tris-acetate, pH 7.4, 140 mM NaCl, 5 mM KCl, 1 mM CaCl2, 1 mM MgCl2
  • Liu's incubation buffer: 40 mM Tris, 20 mM CH3COOH, 2mM EDTA, 12.5 mM (CH3COO)2Mg, pH 8.0
  • Liu's PAGE buffer: 1x TAE/Mg2+
