- Efficiently characterize a plasmid
- Rapidly validate your cloning experiment
Considerations before starting a plasmid sequencing project:
- DNA quality and purity?
- Is there host DNA contamination?
- Sole plasmid or genome and plasmid?
Let us guide you – from design to analysis
Example projects using plasmid sequencing:
- Mutation studies
- Vector verifications
- Characterization of production strains
Applications related to plasmid sequencing:
- De novo sequencing
The assembly of plasmid and other small constructs such as phages allows insights into their genomic structure and the organization of their genetic content.
The first step in our assembly module is the removal of DNA sequences related to the host organism since host contaminations strongly interfere with the assembly process. After host removal the reads are assembled using the assembly software that is suited best for the job. Both, de novo approaches and reference guided assemblies are possible.
The module results in the assembled contigs along with statistics that answer the following questions:
- What is the overall cumulative length of the plasmid? (see Figure 1)
- What is the GC content of the plasmid? (see Figure 2)
- What is the size distribution for the assembled contigs? (see Figure 3)
