This project goal is to build a machine for producing proteins, called Plug&Play. This machine will be a tool for an easy and rapid protein expression, which aims to decrease the time used in screening candidate genes that encode proteins of biological interest. It only uses parts from the Registry of Standard Biological Parts, allowing its free use by the synthetic biology community.

As a proof of concept we proposed to build a single plasmid that allows the expression of any protein in ''E. coli'' using two steps: PCR (Polymerase Chain Reaction) and bacteria transformation. The system is based on the Cre recombinase protein that catalyzes DNA recombination between specific recognition sites.

The goal of this project is to build a prototype machine to produce/screen biological parts in high-throughput manner. This is the first step for characterizing/producing new biological standard parts, which is a huge necessity in the synthetic biology field. To help in this task we developed a prototype plasmid for a machine called Plug&Play, it express any protein helped by the Cre-Recombinase system. This machine will be a tool for an easy and rapid protein expression, which aims to decrease the time used in screening candidate genes that encode proteins of biological interest. It only uses parts from the Registry of Standard Biological Parts, allowing its free use by the synthetic biology community.

Since the Cre expression levels are critical for the system performance, we created two different versions for each of the three plasmids, A (lox71-Cre) and B (Cre-lox71). We want to test if inserting the target gene either upstream or downstream the Cre gene will affect the expression efficiency.
