July, 4th

Digestions of previously purified plasmids were performed for ligations:

Reactions were incubated at 37°C for three hours while a small-size and a medium-size agarose gel were prepared according to protocols.

In the afternoon gel electrophoresis was performed.

Small size gel

Medium size gel

As shown, in figure all clones were positive (apart from <partinfo>BBa_I13501</partinfo> run where we inexplicably didn't see any band), so we cut and purified the bands of interest. Cells harbouring <partinfo>BBa_I13501</partinfo> were again inoculated in 5 ml LB + Amp.

After gel extraction, cut DNA was quantified:

Then ligations were performed in a final volume of 10 μl:

Ligations were incubated ON at 16°C.

July, 5th

T4 Ligase was inactivated, heating ligations at 65°C for 10 minutes; ligations were stored at -20°C. Plasmid purification was done again for <partinfo>BBa_I13501</partinfo> and purified DNA was quantified:

<partinfo>BBa_I13501</partinfo> was then digested with restriction endonucleases:

According to protocols the reaction was incubated at 37°C for 3 hours.
60 ml of 80% glycerol were prepared mixing 48 ml of 100% glycerol with 12 ml of ddH₂O.
Gel electrophoresis was done for <partinfo>BBa_I13501</partinfo> digestion:

Small size gel

Cut DNA was gel-extracted:

Further ligations were prepared and incubated ON at 16°C:

July, 6th

<partinfo>BBa_C0261</partinfo> was resuspended from iGEM 2011 kit distribution, Plate 1, well 14C in 15 μl of ddH₂O; <partinfo>BBa_C0261</partinfo>, E1, E2, E3, E4, E5, E6, E7, and E8 were transformed in 100 μl of TOP10 competent cells according to protocols. Plates were incubated ON at 37°C.
500 ml of LB without antibiotic were prepared.
