Custom Gene Synthesis Services

Inquiry

Custom gene synthesis enables access to genes that are difficult to obtain through traditional cloning methods, mutant libraries carrying multiple point mutations, and codon-optimized genes for high-level expression. Alfa Cytology offers high-quality custom gene synthesis services designed to provide precise, cost-effective gene products for your oncology research projects. Leveraging advanced synthesis platforms and a rigorous quality control system, our experienced scientists are dedicated to high-accuracy, rapid-delivery gene synthesis tailored to meet your specific cancer research needs.

Introduction to Custom Gene Synthesis

Gene synthesis is a cornerstone technology in molecular biology research, enabling the de novo synthesis of target gene sequences through chemical methods without the need for template DNA. This technology overcomes the limitations of traditional PCR cloning with respect to template availability, making it particularly suitable for applications such as genes that are difficult to obtain (e.g., those from rare pathogens or degraded samples), codon-optimized genes, artificially designed mutants, and synthetic biology components. Depending on research requirements, gene synthesis can deliver accurate sequences ranging from short fragments (oligos) to long genes (>10 kb) within relatively short turnaround times, and can be codon-optimized according to the host expression system to enhance protein expression levels. In the field of oncology, custom gene synthesis has become an indispensable research tool, widely applied in oncogene and tumor suppressor gene cloning, construction of tumor driver mutants, synthesis of drug-resistance mutation sequences, and design of artificial gene networks. Traditional cloning methods are often limited by the availability and quality of templates from clinical tumor samples, whereas gene synthesis enables researchers to obtain gene constructs with any desired sequence as well as complex mutant libraries for functional screening. These capabilities provide a solid sequence foundation for tumor target discovery, elucidation of drug-resistance mechanisms, and protein engineering research.

Our Services

Alfa Cytology's custom gene synthesis services support the synthesis of genes of varying lengths and complexities, suitable for cloning, mutant construction, and synthetic biology research. Our scientists can synthesize complete sequences ranging from short fragments (oligos) to long genes (>10 kb), covering a wide range of needs including routine cloning, codon optimization, site-directed mutagenesis, multi-site mutation introduction, construction of complex mutant libraries, and multi-gene assembly.

Standard Gene Synthesis

We synthesize full-length target genes based on the sequence information you provide:

  • Support for any sequence length (50 bp–10 kb+).
  • Sequence verification: full-length sequencing confirmation, 100% accuracy.
  • Delivery format: plasmid DNA (standard cloning vector), glycerol stock.
  • Support for parallel synthesis of multiple genes.

Gene Optimization and Customization

  • Codon optimization: Optimize codon usage based on host cell preferences to improve protein expression levels.
  • Sequence adjustment: Remove or introduce specific restriction sites, adjust repetitive sequences and GC content.
  • Gene variation: Design and synthesize specific mutants (point mutations, truncations, fusions, etc.).
  • Multi-gene assembly: Seamless assembly of multiple genes or fragments.

Applications of Custom Gene Synthesis Services

Our custom gene synthesis services cover multiple key stages of cancer research, from early discovery to preclinical validation, including target discovery, target validation, mechanism studies, and preclinical evaluation. We provide customized support from sequence design to plasmid delivery.

Target Discovery

Our custom gene synthesis services can synthesize hard-to-obtain oncogenes or tumor suppressor genes based on the sequence information you provide, delivering reliable genetic materials for downstream functional studies. We also support the synthesis of custom gene libraries for gain-of-function screening, helping researchers rapidly identify candidate targets with oncogenic potential from large-scale sequence pools.

Target Validation

We can construct gene sequences carrying specific variants such as point mutations, truncations, or insertions to evaluate their effects on protein function and cellular phenotypes. In addition, we support the design and synthesis of fusion genes, applicable to protein tagging, bifunctional studies, and fusion protein expression.

Mechanism Studies

Gene synthesis is a powerful tool for dissecting the mechanisms of tumor initiation, progression, and drug resistance. We can synthesize specific mutant gene variants to assess their effects on protein function and signaling pathways; enhance protein expression yields through codon optimization; and support multi-gene assembly for pathway reconstruction and regulatory network analysis.

Preclinical Evaluation

Stable production of recombinant proteins is critical for drug development. We synthesize codon-optimized gene sequences for efficient recombinant protein expression, and support the synthesis of synthetic biology elements such as promoters and regulatory elements for gene network design and expression regulation studies, providing sequence-level support for preclinical candidate evaluation.

Workflow of Custom Gene Synthesis Services

Project Consultation and Strategy Design

Our scientific team communicates closely with you to understand your research objectives, gene sequences, host systems, and downstream application requirements, and designs the optimal gene synthesis strategy.

Gene Synthesis and Cloning

Based on the approved plan, we perform chemical synthesis, fragment assembly, and cloning into the delivery vector, followed by full-length Sanger sequencing verification.

Sequence Verification and Plasmid Preparation

After sequencing verification, plasmid amplification and purification are carried out to prepare high-quality plasmid DNA and glycerol stocks.

Delivery and Downstream Application Support

We deliver synthesized gene plasmids, glycerol stocks, and complete sequencing reports. If subcloning, expression validation, or downstream functional studies are required, the project can be seamlessly transferred to the corresponding service platform.
