Viral Vector Technology Services


1. Platform Overview

Viral vectors are indispensable core tools in gene function research, gene therapy, cell therapy, and vaccine development. After decades of engineering refinement, viral vectors represented by AAV, lentivirus, and adenovirus have evolved beyond laboratory instruments to become central components of clinical-grade therapeutic products — more than 30 gene therapy drugs utilizing viral vectors as their delivery core have received regulatory approval worldwide.


We specialize in the engineering design, scalable manufacturing, and quality control of viral vectors, with deep expertise across lentiviral, AAV, adenoviral, and novel virus-like particle technologies. Backed by a comprehensive service portfolio spanning seven vector platforms, we provide end-to-end CRO/CDMO services — from plasmid construction through GMP batch release — for academic institutions, biotechnology companies, and multinational pharmaceutical enterprises. A complete Certificate of Analysis (COA) is issued for every batch, ensuring full traceability and data integrity.


2. Core Capabilities

Viral Vector Design & Plasmid Engineering

Serotype/pseudotype selection, ITR/LTR optimization, and promoter engineering, supported by molecular cloning and sequencing verification.

Scalable Manufacturing & Purification

HEK293T-based production platform with ultracentrifugation and chromatography-based purification processes; scalable from research-grade to GMP-grade outputs.

Quality Control Release & Batch Documentation

Comprehensive testing including physical/infectious titer, endotoxin, sterility, RCL, and residual HCD; complete COA and Batch Manufacturing Record (BMR) documentation.

Capsid Engineering & Custom Modification

Directed evolution, peptide insertion, and pseudotyping; supporting custom development of target specificity and immune evasion capabilities.
