The project X-press: Characterization of pSBX-vectors made by Team Heidelberg

The iGEM team Heidelberg constructed a set of expression vectors that contain a T7 promoter prior to the BioBrick prefix. This way RBS-CDS parts can be cloned into the vectors by standard BioBrick assembly and then expressed in BL21(DE3) by induction with IPTG.

In collaboration with the iGEM Team Heidelberg the iGEM Team Aachen tested 8 of these vectors for their expression capabilities.

The Team Heidelberg expression vectors

These are the tested constructs:

Plasmid Backbone Insert Length vector Length Insert Resistance
pSBX1A3-BBa_13507 pSBX1A3 (high copy) BBa_13507 3067 bp 1226 bp 50 mg/ml Ampicilin
pSBX1C3-BBa_13507 pSBX1C3 (high copy) BBa_13507 2982 bp 1226 bp 35 mg/ml Chloramphenicol
pSBX1K3-BBa_13507 pSBX1K3 (high copy) BBa_13507 3116 bp 1226 bp 50 mg/ml Kanamycin
