Project Description

Please note that we are not a pharmacy or clinic, so we are unable to see patients and do not offer diagnostic and treatment services for individuals.

Customized siRNA Linker and Spacer Incorporation

At Protheragen BioNucleics, we are dedicated to advancing the field of oligonucleotide therapeutics by offering comprehensive services in Oligonucleotide Drugs CRO, Oligonucleotide Modification Service, siRNA Modification Service, and siRNA End Modification. Our expertise extends to customized siRNA linker and spacer incorporation, enabling researchers to optimize siRNA molecules for improved efficacy and specificity in gene silencing applications.

Overview of Customized siRNA Linker and Spacer Incorporation

The incorporation of linkers and spacers into small interfering RNA (siRNA) is a strategic approach to enhance their therapeutic potential. Linkers and spacers can modulate the physical and chemical properties of siRNA, affecting factors such as stability, cellular uptake, and target affinity. By customizing these components, it is possible to fine-tune the siRNA molecules to achieve desired biological outcomes. Our advanced techniques allow for precise incorporation of various linker and spacer chemistries, providing tailored solutions to meet the unique requirements of each project.

Our Services

Customized Linker Incorporation

We specialize in the incorporation of diverse linkers that connect siRNA strands or conjugate functional groups:

Cleavable Linkers: These linkers can be engineered to respond to specific intracellular conditions, such as reductive environments or acidic pH, allowing for controlled release of siRNA within target cells.
Non-Cleavable Linkers: Ideal for applications requiring sustained interaction or stability, these linkers permanently join molecules without the possibility of dissociation.
Biodegradable Linkers: Designed to degrade over time, facilitating the gradual release of siRNA and reducing potential toxicity.
Disulfide Linkers: Sensitive to the reducing conditions inside cells, enabling targeted release of siRNA in the cytoplasm.

Customized Spacer Incorporation

Our spacer incorporation services focus on optimizing the spatial arrangement and functionality of siRNA molecules:

Polyethylene Glycol (PEG) Spacers: Incorporation of PEG spacers increases siRNA solubility and circulation time while reducing immunogenicity.
Aliphatic Chain Spacers: Adjust the hydrophobicity of siRNA molecules to enhance membrane permeability and uptake.
Amino Acid Spacers: Utilize naturally occurring amino acids to introduce flexibility or functional groups that can interact with biological targets.
Rigid Spacers: Implement spacers such as trans-cyclooctene to maintain a fixed distance between functional groups, influencing siRNA folding and activity.

Advanced Conjugation Techniques

We employ state-of-the-art conjugation strategies to enhance siRNA functionality:

Chemical Conjugation: Attaching small molecules, peptides, or antibodies to siRNA to facilitate targeted delivery or imaging.
Enzymatic Conjugation: Utilizing enzymes for site-specific modification, ensuring precise placement of linkers or spacers.
Bioorthogonal Chemistry: Applying reactions that occur without interfering with native biological processes, allowing for in vivo modifications.
