Lab work

Ordered DNA

We have now stock of the ordered DNA, to make a real BioBrick of this DNA we are going to ligated it into the iGEM plasmid backbone SB1C3. First we digested the plasmids:

# Digestion reaction Used Buffer Needed fragment
1 1 μg alkB2+ EcoRI + PstI Buffer 3 (BioLabs) ‘E – alkB2– P’
2 1 μg rubA3+ SpeI + PstI Buffer 3 (BioLabs) ‘E – rubA3– P’
3 1 μg ladA + SpeI + PstI Buffer 3 (BioLabs) ‘E – ladA – P’
4 1 μg ADH + SpeI + PstI Buffer 3 (BioLabs) ‘E – ADH – P’
5 1 μg AlnA + SpeI + PstI Buffer 3 (BioLabs) ‘E – AlnA – P’
6 1 μg OprG + SpeI + PstI Buffer 3 (BioLabs) ‘E – OprG – P’
7 1 μg AlkS + SpeI + PstI Buffer 3 (BioLabs) ‘E – AlkS – P’
8 1 μg PalkB + SpeI + PstI Buffer 3 (BioLabs) ‘E – PalkB – P’
9 1 μg PalkS12+ SpeI + PstI Buffer 3 (BioLabs) ‘E – PalkS12– P’
10 1 μg PhPFDα + SpeI + PstI Buffer 3 (BioLabs) ‘E – PhPFDα – P’
11 1 μg PhPFDβ + SpeI + PstI Buffer 3 (BioLabs) ‘E – PhPFDβ – P’
12 3 μg pSB1C3 + EcoRI + PstI Buffer 3 (BioLabs) ‘E – ---- – P’

Solvent Tolerance and Hydrocarbon Sensing

Some BioBricks are in production. Digestion reaction

# Digestion reaction Used Buffer Needed fragment
1 1 μg PhPFDα + EcoRI + SpeI Buffer 2 + BSA (BioLabs) ‘E – PhPFDα – S’
2 1 μg PhPFDβ + EcoRI + SpeI Buffer 2 + BSA (BioLabs) ‘E – PhPFDβ – S’
3 1 μg AlkS + EcoRI + SpeI Buffer 2 + BSA (BioLabs) ‘E – AlkS – S’
4 1 μg PalkB + EcoRI + SpeI Buffer 2 + BSA (BioLabs) ‘E – PalkB – S’
5 1 μg B0032 + XbaI + PstI Buffer 2 + BSA (BioLabs) ‘X – B0032 – P’
6 1 μg B0015 + XbaI + PstI Buffer 2 + BSA (BioLabs) ‘X – B0015 – P’
7 1 μg E0422 + XbaI + PstI Buffer 2 + BSA (BioLabs) ‘X – E0422 – P’
8 3 μg pSB1T3 + EcoRI + PstI Buffer 2 + BSA (BioLabs) ‘E - ---- - P’

Emulsifier

Today the digestion products from yesterday were run on gel to see whether the plasmids were cut in the right way.

1% Agarose gel runned at 100V for 1h

! Sample not fully loaded on gel

The band position of the digestion products of AlnA and OprG correspond to their length. The other fragments (R0011, B0032 and B0015) probably run of the gel.

The ligation products that were incubated over night were transformed to Top10 competent cells according to the protocol.
