N3-Poly(L-Arginine) (N3-PArg) is an azide-functionalized cationic poly(amino acid) based on poly(L-arginine). It combines guanidinium-rich PArg with an azide group specifically for click chemistry, bioconjugation, and functional biomaterial research.
Key Features and Benefits
- Cationic Poly(amino acid): Poly(L-arginine) provides multiple positively charged guanidinium groups for electrostatic interactions with anionic molecules and materials.
- Azide Functionality: Provides an azide group specifically for selective click chemistry with compatible alkyne-functionalized molecules.
- CuAAC Click Chemistry: Supports copper-catalyzed azide-alkyne cycloaddition with terminal alkyne-containing compounds.
- SPAAC Compatibility: Reacts with strained cyclooctynes such as DBCO or BCN specifically through copper-free click chemistry.
- Guanidinium-Rich Structure: Arginine side chains provide especially strong cationic character and support interactions with negatively charged biomolecules.
- Electrostatic Complexation: Supports association with nucleic acids, anionic polymers, and other negatively charged materials.
- Bioconjugation Platform: Enables attachment of compatible peptides, proteins, ligands, polymers, and other functional molecules through click chemistry.
Applications
- Click Chemistry: Supports CuAAC and SPAAC reactions with compatible alkyne or strained cyclooctyne groups.
- Bioconjugation: Enables click-mediated attachment of biomolecules, ligands, polymers, and other functional components.
- Nucleic Acid Complexation: The cationic PArg segment supports electrostatic interactions with negatively charged DNA, RNA, and related molecules.
- Polymer Functionalization: Provides an azide handle for incorporating poly(L-arginine) into compatible functional polymer systems.
- Nanoparticle Functionalization: Supports click-mediated modification of compatible nanoparticles and polymer assemblies.
- Drug Delivery: Supports development of functional cationic polymers for drug-delivery and formulation research.
- Surface Modification: Enables click-mediated attachment to compatible functionalized surfaces and materials.
- Biomaterial Research: Supports development of functional polymer conjugates, complexes, coatings, and related biomaterials.
Storage and Handling
- Storage: Store at –20 °C in a tightly sealed container under dry conditions.
- Handling: Protect from moisture and excessive heat. Allow the material to reach room temperature before opening to minimize condensation.
