Design Notes
Our Chlor backbone uses a pPTK-PARS vector as a base, which enables chloramphenicol resistance in bacteria1. It contains an E. coli origin of replication (nt 1684-2272) which enables plasmid replication in our model organism2. However, specific modifications have been made to maximize efficiency for Golden Gate synthesis and transformation. The pPTK-PARS vector was shortened and a blue-white selection marker from pUC193 (nt 36-711) was inserted, along with flanking PaqCI cut sites (nt 25-39, 716-730). BsaI cut sites (nt 14-24, 731-741) flank the PaqCI cut sites, allowing for sequential insertion of genes using Golden Gate Synthesis. Insertions were completed via PCR and ligation.
Plasmids were transformed via electroporation or chemical transformation into NEB 10-beta competent cells. Transformation in cells was confirmed following sequencing of extracted DNA by Plasmidasaurus
Sources
This part was ordered for de novo gene synthesis from Twist Bioscience, and is based on the pPTK021-7-PARS cloning vector, using a pUC19 blue/white selection sequence.
