Gene Synthesis Services

15 years of experience in gene synthesis services

With more than 15 years of experience in custom gene synthesis, gene subcloning, recombinant protein production, and antibody development, 90+ technical experts, and PhD account managers with considerable field expertise in gene synthesis services, resulting from over a decade of experience, and state of the art equipment, ProteoGenix has demonstrated its core expertise in this domain.


Our high success rate in protein and antibody production also relies on the quality of our gene sequence engineering work and codon optimization service, both of which are based on strong empirical data, while providing cost effective, one-stop-shop solutions.

Multiple accreditations, 700+ customers and over 85% repeat business for gene synthesis alone; this is a true reflection of the confidence that customers place in us. We have a diverse customer base including academia – universities, public research laboratories, as well as industry, including pharmaceutical companies, laboratories, diagnostics, veterinary science, the agri-food industry etc. We offer customer-focused and flexible gene synthesis solutions. With rapid turnaround times (<7 days) and competitive pricing starting from 0.15€/bp we ensure complete customer satisfaction. Our featured publications cited below illustrate examples of successful case studies that have used our genes.


Free codon optimization using ProteoGenix’s proprietary, high efficiency, codon optimization algorithm, choice of vector used, site-directed mutagenesis and gene variant libraries; these are just a few things that set us apart from the competition. We have a library of cloning vectors and also offer you the flexibility of using your own vector. Our existing gene libraries, containing several dozen pre-synthesized, human wild type genes drive down costs and make our processes more efficient. Gene synthesis has been widely used for improving the expression of genes and has leveraged expensive techniques such as RT-PCR, RACE etc. Fast and reliable access to multiple cDNA sequences, the removal of unwanted restriction sites by the introduction of desired mutations, and the ability to drive speedy and effective antibody drug discovery, not only through rapid gene synthesis services, but also by leveraging our high-throughput platform for protein synthesis; these are just some of the advantages of working with ProteoGenix.

Our complementary gene synthesis services include

Free codon optimization

  • ProteoGenix has developed a unique codon optimization algorithm based on experimental data.

  • Most of amino acids are encoded by multiple codons that are called synonymous codons. However, specific codons are used more often than others during gene translation. This phenomenon is called the codon usage bias and is species specific. So, as a result of the redundancy of the genetic code, rare codons can be replaced by codons that are more abundant in the genes of the host organism, without changing the amino acid sequence of the protein, per se. ProteoGenix’s Codon Optimization Tool leverages a codon bias strategy and additional parameters like GC content, repetitive sequences, avoiding restriction sites and mRNA secondary structure.

  • Applications of codon optimization include:

  1. Ease of DNA Synthesis: ProteoGenix’ Complimentary Codon Optimization Tool, while accounting for natural codon bias and synthesis complexity, significantly enhances the efficiency of designing customized synthetic genes.

  2. Recombinant protein production in a repertoire of expression systems: Codon optimization is essential for recombinant protein production as it allows easy gene subcloning steps and enables gene expression as well as yields improvement.. The heterologous expression of recombinant proteins is a critical aspect of modern biotechnology and biomedicine.

  3. Gene therapy: Gene therapy, leveraging codon optimization, is being applied to treat multiple conditions including Duchene muscular dystrophy (Athanasopoulos, T et al, 2011) and Hepatitis C (Frelin L et al, 2004).

  4. Genetic immunization: An immune response can be obtained by injecting the gene encoding the antigen directly into the animals. In this way, DNA vaccine is a perfect tool when a protein is difficult to express or purify. Genetic immunization using DNA vaccines requires the high expression of the gene of interest. It has been demonstrated that wild type genes generate a low or moderate levels of immune response as compared to genes that have been codon-optimized (Stratford et al., 2000; Uchijima et al., 1998). In addition, while adjuvants are known to enhance the immune responses in the case of recombinant protein vaccines, no such adjuvants are in the case of DNA vaccines, resulting in the poor performance of the DNA vaccines in larger animals. Engineering CpG islands into DNA vaccines has on the other hand enhanced the immunogenicity of DNA vaccines (Krieg et al., 1998). Thus, customized DNA synthesis and gene assembly can add considerable value.

Gene variant libraries with particular changes in one or more designed position(s)

  • ProteoGenix can provide gene variant libraries with changes in one or several positions to optimize protein expression. This service can be very useful for high-throughput screening for applications such as protein engineering (change/mutation of AAs in one or several positions).

Endotoxin free plasmid preparation

  • As a leading gene synthesis manufacturer, ProteoGenix also offers endotoxin free plasmid amplification services. Indeed, after gene optimization and gene cloning, it is usually necessary to amplify the construction in order to have endotoxin free plasmid available in sufficient amounts for experiments.

Applications of custom gene synthesis

Immunology and antibody discovery

Immunology and antibody discovery

Recombinant antibodies can be synthetically engineered to reduce immunogenicity while enhancing specificity, stability, cross-reactivity and affinity, for increased safety and efficacy. Monoclonal antibodies are the new generation biotherapeutics.

Gene synthesis for Synthetic biology

Synthetic biology

Synthetic biology applies custom gene synthesis and utilizes it to build artificial biological systems for research, engineering and medical applications. The CRISPR/Cas9 system for gene editing has been hailed by The Washington Post as “the most important innovation in the synthetic biology space in nearly 30 years”.

Gene synthesis for Agrigenomics research



Agrigenomics research is being emphasized to optimize agricultural productivity and nutrition.


The use of biomarkers and companion diagnostics as neuro/chemical/biological indicators in research are driving the onset of precision medicine. Medical practitioners depend on a patient’s pharmacogenomic profile to detect genetic disorders.

DNA synthesis for Cancer research

Cancer research

Custom gene synthesis advancements have seen a major increase in the data produced by cancer research initiatives. Using Next Generation Sequencing and whole genome targeting, scientists are better understanding protein functioning in oncogenesis.

DNA synthesis for Phage display

Phage display

Phage display is a powerful tool to screen antibody related DNA libraries. Generating DNA libraries for antibody engineering requires strong molecular biology skills to generate relevant cDNA to build a powerful library.
