CMV-EGFP-MagA-P2A-hGLuc
Usage and Biology
The composite part described here exhibits an EGFP-MagA-P2A-hGLuc-cassette under the control of a CMV-enhancer/promoter for expression in mammalian cells. It was used to determine the expression of MagA and hGLuc at the same time from one promoter.
Cloning
Theoretical Part Design
In order to test whether HeLa cells are able to simultaneously express MagA and hGLuc using a P2A-peptide, MagA and hGLuc were cloned into the pEGFP-C2 vector interspaced with P2A. In the resulting plasmid MagA is encoded with a N-terminal EGFP-tag making MagA detection very easy. The CMV promoter ensures constitutive and high expression rates mimicking the fully activated sensor.

Cloning
The plasmid pEGFP-C2 (BBa_K3338020) was linearized with EcoRI and SalI. The MagA, P2A und hGLuc fragments were PCR amplified using the primers shown in table 1.

These primers exhibit 5’ overhangs from approximately 20 bp length, that are designed using SnapGene allowing the assembly via the NEBuilder® HiFi DNA Assembly Cloning Kit. The sequence of the part was verified by sanger sequencing. The vector map of the final construct is shown in figure 1.
