Creative Biogene offers comprehensive custom vector construction and modification services tailored to meet the diverse needs of researchers in the academic and biopharma sectors. Vector construction entails various complex steps including sequence design, template selection, fragment assembly, validation, and functional testing. Traditional methods can often be time-intensive and challenging, particularly for high-GC sequences, repetitive regions, or large fragments. Our proprietary vector engineering platform employs high-fidelity DNA synthesis, modular assembly, seamless cloning, and high-throughput validation, thus enabling an extensive range of customization—from basic insert cloning to more sophisticated multi-gene co-expression systems, gene-editing vectors, and reporter system development.

Our services encompass plasmid, lentiviral, AAV, eukaryotic, prokaryotic, reporter, and specialized functional vectors. Each construct is developed through rigorous design strategies and standardized workflows, ensuring clarity of functionality, stability, and reproducibility.

Technical Capabilities
Creative Biogene leverages a comprehensive molecular biology infrastructure supported by advanced automated instrumentation. This aids our end-to-end workflow management from design to product delivery:

Precision Design & Optimization: Proprietary algorithms facilitate codon optimization and structural predictions to achieve maximum expression efficiency in target hosts.
Multi-Gene & Modular Integration: Our platform supports tandem, polycistronic, and inducible systems for intricate expression patterns and regulatory network constructs.
Advanced Vector Engineering: This includes techniques like site-directed mutagenesis, fragment insertion/deletion, backbone modification, tag management, and promoter tuning, enhancing vector functionality.
High-Throughput & Automated Workflow: By leveraging automation, we can perform parallel constructions of multiple vectors, significantly reducing project timelines.
Essential Genetic Elements
Each vector can incorporate crucial genetic elements such as linkers, promoters, protein tags, and signal peptides tailored to enhance performance and adaptability.

Linker
Flexible peptide connectors that optimize spatial configuration and functional independence between fusion protein domains.

Promoter
Constitutive, inducible, and tissue-specific elements that are customized to meet expression requirements and host compatibility.

Protein Tag
Affinity purification tags and fluorescent markers enabling streamlined downstream detection and purification.

Signal Peptide
Secretion signals that direct proteins to specific cellular compartments or the extracellular environment, essential for correct folding and post-translational processing.

Standardized Service Workflow
Our construction process operates under a framework of scientific rigor and regulatory compliance, ensuring complete data traceability:

Requirement Assessment & Design: Clients provide target sequences; our team evaluates feasibility and confirms the design.
Sequence Synthesis & Fragment Verification: DNA fragments are synthesized or amplified and verified through sequencing.
Vector Assembly & Clone Validation: Fragments are assembled into vectors, with clones screened and sequenced to ensure correct inserts.
Quality Control & Documentation: Final products undergo quality checks, with QC certificates and vector maps provided.
Delivery & Support: Vectors are delivered as lyophilized DNA or glycerol stocks, along with optional support for transfection or expression validation.
Quality Assurance
Creative Biogene prioritizes quality excellence. All projects follow stringent QC protocols with the following measures:

Bi-directional Sanger sequencing confirms complete sequence fidelity for every delivered plasmid batch.
Specifications concerning vector concentration, purity metrics, and endotoxin levels comply with research-grade or GMP-level requirements.
Comprehensive batch numbering and project tracking ensure absolute data traceability.
Case Study
In a recent project, researchers examined the human jumping translocation breakpoint (hJTB) gene in breast cancer using custom plasmids designed by Creative Biogene. For JTB overexpression, a vector containing multiple tags was constructed, while four shRNA plasmids targeting different sequences were developed for downregulation. The results indicated that altered JTB expression plays a significant role in breast cancer aggressiveness.
