Workflow

Streamlined Development Process

Our comprehensive workflow ensures the highest standards of quality and efficiency from initial submission to final data delivery.

Step 01: Sample Submission & Feasibility

Initiation

The process begins when the client submits viral vector samples along with detailed process information. Our technical team conducts a preliminary evaluation of the sample matrix and concentration levels to recommend the most suitable purity assays and experimental design.

Step 02: Method Optimization & Testing

Execution

For complex matrices, we perform rigorous method qualification or optimization strategies to ensure accuracy. Samples are then tested using selected high-precision technologies (e.g., AUC, ELISA, qPCR) alongside appropriate internal controls to validate the results.

Step 03: Data Analysis & Reporting

Delivery

Raw data undergoes a strict analysis by our Quality Control (QC) team. We deliver a comprehensive report that includes detailed chromatograms, high-resolution images, impurity calculations, and a formal Certificate of Analysis (CoA) to support your downstream applications.

Therapeutic Applications

Targeted Disease Research

Polymer-conjugated ASOs are particularly useful in developing therapies for conditions that require sustained drug release or targeted delivery to specific organs.

Genetic Disorders

Enhancing delivery to muscle or CNS for diseases like Duchenne Muscular Dystrophy (DMD) or SMA.

Cancer Therapy

Leveraging the EPR effect (Enhanced Permeability and Retention) of polymers to target tumor tissues.

Enhanced Delivery

Improved penetration into target tissues and cellular internalization efficiency compared to naked ASOs.

Biological Analysis

In biological studies, polymer-conjugated ASO can be used as probes or primers for DNA sequencing, gene cloning, and other experiments..

Molecular Diagnostics

The ability of ASO to bind to specific DNA or RNA sequences is used for early diagnosis and screening of diseases.

The Science Behind It

Understanding how polymer conjugation overcomes biological barriers is key to successful ASO therapeutic development. We tackle two main obstacles:

Stealth Effect

Polymer shielding significantly reduces protein adsorption (opsonization), preventing rapid clearance by the reticuloendothelial system.

Endosomal Escape

Specific polymer designs induce a proton-sponge effect or membrane disruption, facilitating the release of ASOs into the cytoplasm.

Expert Answers

Common questions regarding our conjugation services.

Polymers primarily increase the molecular weight of the ASO, which helps avoid rapid renal clearance, thus extending the circulation half-life. Additionally, polymers can improve solubility, protect against nuclease degradation, and potentially reduce immunogenicity.

Selection is based on the desired physicochemical properties. We consider factors such as hydrophilicity (e.g., PEG), biodegradability (e.g., polyglutamic acid), charge, and the specific therapeutic target. We also evaluate the conjugation chemistry compatibility with the ASO sequence.

Challenges include ensuring site-specific conjugation without disrupting the ASO's binding affinity to its target mRNA, achieving high yield and purity, and characterizing the polydispersity of the polymer conjugate. Our advanced analytical platform addresses these issues effectively.

Regulatory bodies require detailed characterization of the conjugate, including the polydispersity of the polymer, the linker stability, and the impurity profile (e.g., free polymer, free ASO). We provide comprehensive CMC data to support regulatory filings.
