Hydrocarbon Sensing

Cell bank

A cell bank was made from E.coli Top10 cells transformed with AlkS-E0422 and AlkS-B0015. We used 2 mL of the bacterial cells to make -80 °C stocks.

Alkane Degradation

PCR Amplification

K398007A, K398008A, K398009A, K398010A, K398017A, K398018A, K398019A, B0015 were amplified with the universal primers G00100 and G00101. The product was put on 1% agarose gel:

1% agarose of PCR. Gel runned at 100V for 1 hour. Of all samples 10 μL + 2 μL loadingbuffer was loaded. 5 μL was loaded of marker

Digestion

The PCR products were subsequently digested:

# Sample Enzyme 1 Enzyme 2 Buffer BSA Needed fragment
1 40 μL PCR product 007 EcoRI SpeI 2 (BioLabs) ‘E–007–S’
2 40 μL PCR product 008 XbaI PstI 2 (BioLabs) ‘X–008-P’

8 40 μL PCR product B0015 XbaI PstI 2 (BioLabs) ‘X–B0015-P’

Ligation

The digestion products were ligated overnight:

# BioBrick Fragment 1 Fragment 2 Final volume
1 K398011 4 μL ‘E–007–S’ 4 μL ‘X–008–P’ 10 μL
2 K398012 4 μL ‘E–009–S’ 4 μL ‘X–010–P’ 10 μL
3 K398020 4 μL ‘E–017–S’ 4 μL ‘X–018–P’ 10 μL
4 K398021 4 μL ‘E–019–S’ 4 μL ‘X–B0015–P’ 10 μL
5 negative control 4 μL ‘E–007–S’ 4 μL H2O 10 μL

Plasmid isolation

A plasmid isolation was done on the positive colonies of yesterday. This was done using a Qiagen Miniprep kit. We used 2 mL of the bacterial cells to make -80 °C stocks.
