Positive Control Experiment

Construct Design

In the positive control experiment we replaced the Green Fluorescent Protein coding sequence with a coding sequence for mRUBY, which is a Bright Monomeric Red Fluorescent Protein. The picture below shows a map of the modified plasmid. File:cam_plasmid_positivecontrol.jpg | frameless | thumb | 600px | map of the modified plasmid with mRUBY insertion]]

Experiment

The experiment involved the same steps as preparation and expression of gene fusions of the three teams.

PCR reaction

  • We amplified the mRUBY coding sequence and two arms of the plasmid in a PCR reactions. First, we performed a real-time PCR with Taq polymerase, but as most samples were poorly amplified, we decided to repeat the reaction with Phusion polymerase (protocol)

The three reactions performed ae the following:

Reaction A
1μl primer ruby F (provided)
1μl primer ruby R (provided)
1μl mRuby template
Reaction B
1μl primer Vector F (provided)
1μl primer B reverse (provided)
1μl plasmid template
Reaction C
1μl primer Vector R (provided)
1μl primer A forward (provided)
1μl plasmid template
