Chang Backbone of rbs-mbp:
1. Double digestion: inserts (E/P)
2. Electrophoresis in 1% agarose gel.
3. Excise the gel slice and extract target fragments.
4.Ligate inserts to pSB1C3 (E/P)
5. Transformation
10.15
1. Picking colonies from rbs, shaking at 37℃ for 10 hours.
2. Colonies PCR:
For 0.5uL
Rev 0.5uL
Easymix 5uL
template 0.2uL
ddH2O up to 10 uL
Identification by Electrophoresis.
3. Digestion:
Buffer3 1uL
BamHI 0.75uL
rbs-mbp 5uL
ddH2O up to 10uL
identification by Electrophoresis
Sequence.
