Introduction How Can We Help? Deliverables Key Benefits Related Products FAQs Contact
Are you currently struggling with poor stability or limited conjugation options for diverse therapeutic molecules like small molecule drugs, peptides, or oligonucleotides? Our ApDC Development service helps you accelerate the creation of potent, highly specific drug conjugates for any payload type through proprietary Nuclease-Resistant Backbones and Versatile Conjugation Chemistries. We provide the expertise to transform aptamer leads into clinically viable therapeutics with superior tissue penetration and reduced systemic toxicity.
Introduction of ApDC Development by Therapeutic Payload
What Is Our Service?
Creative Biolabs' ApDC Development service focuses on the chemical engineering and synthesis of nucleic acid ligands (aptamers) covalently or non-covalently linked to various therapeutic agents. This creates a targeted "chemical antibody" system that directs the payload specifically to diseased cells, enhancing local drug concentration while mitigating off-target effects. Our comprehensive service includes:
-
Aptamer-Protein/Peptide Conjugate Development
Designing and synthesizing aptamers linked to therapeutic proteins (like toxins or enzymes) or functional peptides to leverage the cell-targeting ability of the aptamer with the biological function of the large payload.
-
Aptamer-Small Molecule Drug Conjugate Development
Chemically coupling aptamers with conventional cytotoxic or small molecule therapeutic drugs via custom linkers, enhancing the solubility and specific delivery of the drug.
-
Aptamer-Oligonucleotide Conjugate Development
Creating conjugates where the aptamer targets a cell, and the payload is a nucleic acid drug, such as siRNA, antisense oligonucleotides (ASOs), or miRNA, to trigger sequence-specific gene silencing.
-
Aptamer-Imaging/Theranostic Conjugate Development
Linking aptamers to diagnostic agents (like fluorescent dyes or radioisotopes) or combining both therapeutic and imaging agents into one molecule for simultaneous treatment and monitoring.
-
Aptamer-Nanocarrier Conjugate Development
Conjugating aptamers to the surface of liposomes, nanoparticles, or polymeric carriers to achieve targeted delivery of a high payload quantity encapsulated within the nanocarrier.
Why Choose Us?
Aptamers offer intrinsic biological advantages over large antibodies, boasting a smaller molecular weight (6–30 kDa), high chemical stability, and facile synthesis. However, these advantages are often lost during conjugation and in vivo circulation due to rapid nuclease degradation and swift renal clearance. Creative Biolabs addresses these critical pain points directly:

Key Benefits
Creative Biolabs' unique platform accelerates your project by addressing the known limitations of conventional ApDC development head-on, delivering molecules that are intrinsically more robust and effective.
Nuclease-Resistant Backbones
We integrate proprietary chemical modifications directly into the aptamer structure to prevent rapid enzymatic degradation, drastically extending the effective in vivo half-life compared to unmodified oligonucleotides.
High Payload Capacity
Our advanced conjugation architectures enable high drug loading while simultaneously maintaining the aptamer's critical binding affinity, overcoming the traditional steric hindrance problem.
Precision and Homogeneity
Unlike random conjugation methods, our site-specific coupling strategies result in highly reproducible batches and predictable pharmacological outcomes.

Frequently Asked Questions
Q1: How does Creative Biolabs address the short in vivo half-life that plagues many ApDC designs?
A: We primarily address this with two complementary strategies. First, we chemically modify the aptamer backbone using non-natural nucleotides (like 2'-Fluoro) to shield it from serum nucleases. Second, we employ precision, site-specific PEGylation to prevent rapid renal clearance. Together, these methods extend the circulation time, ensuring sustained drug delivery to the tumor.
Q2: In terms of efficacy and safety, how do ApDCs compare to Antibody-Drug Conjugates (ADCs)?
A: ApDCs offer a smaller size, which translates to faster and deeper tumor tissue penetration, potentially making them more effective in dense solid tumors. Furthermore, aptamers are non-immunogenic and chemically synthesized, offering a better safety profile and lower cost of goods compared to complex, biologically derived ADCs.
Q3: How does the initial ApDC optimization phase typically proceed, and what commitment is required from our team?
A: The initial optimization phase typically ranges from 10 to 18 weeks, driven by the complexity of the linker chemistry and the type of payload. Your commitment primarily involves providing us with the necessary target information and therapeutic payload details. We manage the entire synthesis, purification, and in vitro validation process, providing you with actionable data on lead candidates.
