Are you currently facing systemic toxicity, limited therapeutic payload range, or complex conjugation challenges in your oncology pipeline? Our Aptamer-Drug Conjugate Development Service helps you achieve superior targeted delivery and dramatically reduce off-target toxicity through advanced SELEX and proprietary conjugation chemistry.
Introduction of Aptamer-Drug Conjugate Development
The future of targeted therapeutics demands delivery vehicles that combine high affinity with superior pharmacological properties. Aptamers, single-stranded oligonucleotides (DNA or RNA), fulfill this need. Termed "chemical antibodies," aptamers are synthesized chemically, offering exceptional thermal stability and minimal immunogenicity compared to protein-based antibodies. This small size (typically 3–30 kDa) enhances tumor penetration and allows for faster systemic clearance, directly translating to a reduction in off-target exposure—a fundamental advantage for next-generation drug design.
What Is Our Service?
Aptamer-Drug Conjugate (ApDC) Development is our specialized platform for creating highly selective, chemically stable therapeutic assets. This service leverages the unique tertiary structure of aptamers as a molecular GPS to guide potent payloads directly to diseased tissue, bypassing the systemic toxicity associated with traditional chemotherapeutics. Our ApDC development is strategically categorized into 2 types:

Key Benefits
Creative Biolabs does not simply link an aptamer and a drug; we engineer a complete precision system. Our unique features address the core needs of therapeutic development: stability, specificity, and safety.
Engineered High-Affinity Binding
Our optimized SELEX process yields aptamers with high affinity.
Scalable Chemical Synthesis
Unlike antibody production, our ApDCs are generated via advanced chemical synthesis and purification techniques. This translates to precise control over the Drug-to-Aptamer Ratio and guaranteed homogeneity for clinical batches.
Versatility for Advanced Payloads
Our conjugation platform extends beyond simple small molecules. We possess the chemical expertise to conjugate aptamers with complex, next-generation payloads, enabling new mechanisms of action for difficult targets.

Frequently Asked Questions
Q1: How can ApDCs be safer than the established Antibody-Drug Conjugates (ADCs)?
A: ApDCs are fundamentally smaller and chemically synthesized, offering superior control over stability and purity. Our engineered cleavable linkers ensure the payload is released specifically within the tumor microenvironment, dramatically reducing systemic drug exposure and resulting in minimal side effects.
Q2: How long does the Aptamer-Drug Conjugate Development process typically take?
A: The total project timeline is highly dependent on the target complexity and required in vivo stability modifications. A typical project runs between 16 and 24 weeks. We encourage you to contact us directly to provide your requirements, and we can offer a precise, stage-gated projection.
Q3: What information should I have ready to start a project with Creative Biolabs?
A: To accelerate your timeline, please provide the full sequence of your target antigen, the chemical structure of your drug payload, and any existing in vitro binding data you may have. We're here to guide you through the process, so reach out to our specialists today!
