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.

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 control experiment consists of 3 reactions
