Clinical & Commercial Oligonucleotide Manufacturing

With two synthesis platforms under one roof—solid-phase synthesis for scales from μg to several kg and AJIPHASE™ for sustainable production up to 200 kg—we offer flexible GMP oligonucleotide manufacturing solutions, supporting programs from process development through commercial supply.

Technology at a Glance

Based on each customer’s development stage, scale, and program needs, we recommend the optimal approach: Solid Phase, AJIPHASE™, Enzymatic Synthesis, or a tailored combination of platforms.

Solid-Phase Synthesis

Best for: Rapid Development

Scale Range: μg to several kg/batch

Key Advantage: Established platform, rapid development

AJIPHASE™ Synthesis

Best for: Large-scale manufacturing

Scale Range: Grams to 200 kg/batch

Key Advantage: Scalable and sustainable manufacturing

Enzymatic siRNA Synthesis

Best for: Complex & longer structures

Scale Range: Grams to tons

Key Advantage: Higher purity and yield with reduced PMI

GenClip™ Long RNA Synthesis

Best for: sgRNA, pegRNA, and mRNA

Scale Range: Research to mg Scale

Key Advantage: Maintains high yield and quality for long RNA

Oligonucleotide Supply Path

Transforming Every Stage of Development

One partner from first synthesis through commercial supply. Seamless platform selection, continuous process knowledge, and support at every scale.

Solution Optimization

Optimize Your Solution

From development through clinical and commercial supply, we support oligonucleotide programs with an integrated CMC workflow. Our teams begin with synthesis optimization, including coupling efficiency and deprotection conditions, to build a scalable and robust manufacturing process. We then develop downstream processes using purification strategies such as IEX, RP-LC, and UF/DF to achieve target purity and recovery.

Stability Support

Stability and Regulatory Support

We provide phase-appropriate analytical development, method validation, stability studies, and product characterization to support global regulatory requirements. Integrated CMC documentation and technical support help programs progress from clinical development through commercialization.

Quality Systes

Quality and Certification

Our quality systems support GMP operations through controlled batch record documentation and QA/QC oversight. We also support stability programs designed in accordance with ICH guidelines and provide CMC regulatory support throughout the product lifecycle. This quality foundation is backed by decades of oligonucleotide expertise, global GMP manufacturing, and scalable production capabilities.
