Custom CpG-Free Genes

Custom CpG-free geneDesign and Synthesis of CpG-Free Genes

InvivoGen is an expert in developing CpG genes and now offers a CpG-free gene custom service. Send us the sequence of your gene of interest, and our specialists will design, synthesize and clone into an expression vector a CpG-free allele of this gene. We guarantee that the sequence of the synthetic gene will 100% match the designed sequence.

Key Service Features

- Free Sequence Design
- Short Turnaround Time
- Competitive Price
- Confidentiality Guaranteed



Sequence Design

Our experts will design the sequence of a CpG-free allele of your gene of interest using a proprietary software that will include the following:
- elimination of all CpG dinucleotides
- humanization of the sequence
- elimination of secondary structures such as hairpins and long direct repeated sequences in order to increase the stability and expression of the mRNA
- elimination/reduction of dam and dcm methylations to diminish E.coli signature

Cloning in an Expression Vector

The Custom-made CpG-free Gene is cloned into the pMA plasmid. We can clone it in the vector of your choice for an additional charge.


The Custom-made CpG-free Gene is 100% sequence verified, both strands are sequenced.


Send us the nucleic (Genbank accession number) or proteic sequence of your gene of interest. The synthesis of the CpG-free allele will start after you confirm its sequence.
The turnaround time is 2-3 weeks for sequences shorter than 1 kb.
We can process sequences up to 5 kb.


Custom-made CpG-free genes are provided as 20 µg of lyophilized DNA. Products are shipped at room temperature. Store at -20°C.
