We have the capability and confidence to meet your needs for novel conjugates.
Antioxidant-oligonucleotide conjugation refers to the covalent attachment of antioxidant molecules to oligonucleotides, which is a binding strategy that combines the therapeutic potential of oligonucleotides with the antioxidant properties of specific molecules and aims to enhance the stability and efficacy of oligonucleotide-based therapies. Antioxidants scavenge reactive oxygen species (ROS) and prevent oxidative damage to molecules that can reduce the oxidative stress that can occur during oligonucleotide delivery, cellular uptake and intracellular processing. However, oxidative stress is one of the major causes of oligonucleotide degradation, inactivation and off-targeting.
Bifunctional junctions with antioxidant and oligonucleotide reaction groups are used, which allow selective binding of the antioxidant to specific sites on the oligonucleotide molecule. The choice of antioxidant depends on stability, ROS scavenging ability and compatibility with conjugation chemistry to meet the needs of research.

Antioxidant-oligonucleotide conjugation involves attaching antioxidant molecules to oligonucleotides, which helps protect the oligonucleotides from oxidative damage. This approach enhances the stability and efficacy of oligonucleotide-based applications.
Antioxidants scavenge reactive oxygen species (ROS) and prevent oxidative damage during oligonucleotide delivery, cellular uptake, and intracellular processing. This improves the overall stability and performance of oligonucleotide-based therapies.
Common antioxidants used in conjugation include ascorbic acid (Vitamin C), tocopherols (Vitamin E), glutathione, catechins, and carotenoids. Each antioxidant is selected based on its stability, ROS scavenging ability, and compatibility with conjugation chemistry.
Antioxidants are covalently attached to oligonucleotides using bifunctional linkers that provide reactive sites on both the antioxidant and the oligonucleotide. This selective binding ensures stability and efficacy.
