Folding reaction
Fold 200 μL each of 3.2.Eo, .Fo, .Go, .Ho
Each reaction:
- 45 μL p7308 scaffold (44 nM)
- 80 μL oligo stock (250 nM)
- 20 μL 10x folding buffer (500 mM HEPES pH 7.5, 500 mM NaCl, 100 mM MgCl2)
- 55 μL dH2O
Folding conditions:
- high-volume protocol: start at 80[[:Category:{{{1}}}|{{{1}}}]], decrement 0.5[[:Category:{{{1}}}|{{{1}}}]] every 1 min. for 120 cycles.
More Microcon trials
Microcon purification of yesterday's folding reactions
- speedvac'd c3.2F, G, H, I, Eb, Fb flowthrough for 50 min. (vol. def much higher than 40 μL)
- ran 2% agarose + MgCl2 gel

- 3 flowthroughs is probably not enough - notice pretty clear oligo smears: should probably do 5/6
- don't know if oligo-ligand and latches were added to rxns before microcon: repeat folding of c3.2F, G, H, I and retest
