Transformed 1ul of each of the above into DH5a competent cells:

Transformation

  • Mix 1ul of DNA with 100ul of competent cells on ice.
  • Leave on ice for 30 minutes.
  • Heat shock at 42℃ for 45 seconds.
  • Leave on ice for 2 minutes.
  • Add 500ul of LB and incubate at 37℃ for 1 hour.
  • Plate on LB-ampicillin plates.

Creating a biobrick part out of yqiT

Strategy: PCR out the yqiT gene from the Bacillus subilitis genome using primers to attach the biobrick preffix/suffix and clone this into a biobrick vector. The vector utilized is the GFP generator which houses a sufficient-sized insert:

PCR of yqiT gene
The Bacillus subilitis genome was provided by <?????????>


The following primers were used to amplify an approx. 1500bp fragment from the Bacillus subilitis genome.

yqiT EX: <????????>


yqiT SP: <????????>

PCR protocol
The following was mixed in a PCR tube:
1ul 20uM yqiT EX primer
1ul 20uM yqiT SP primer
2ul 10X <????> buffer
<???> dNTP mix
0.15ul Bacillus subilitis genome
<???> <????> enzyme
<???> MilliQ

Performed PCR using the following program:

1. 95℃ 2 minutes
2. 95℃ 1 minute
3. 50℃ 30 seconds
4. 72℃ 1 minute 20 seconds
5. Repeat 2-4 29 times
6. 4℃ ∞

Purified PCR product using the Promega PCR purification kit.

Ran on gel to visualize bands:
