Introduction

‘Hello World!’ are the first words a programmer prints on his screen when learning a new programming language. In analogy to this our team decided to do a ‘Hello World’ project in order to familiarize ourselves with lab techniques that we used later on to construct plasmids. Specifically we were performing PCR with uracil-containing primers, purifying PCR products and ligating them by means of USER cloning.

Since we are working with many periplasmic proteins, we wanted to try to target proteins to the periplasm. To do this, we used periplasmic signal peptides from the TAT and Sec pathways, and with a translational fusion of the signal peptide to GFP, we expressed GFP in the periplasm. Simultaneously, we expressed RFP in the cytoplasm.

Results

The project was concluded sucessfully. We have created the biobrick BBa_K1067009
