PDLLA-PEG-Biotin, MW x 20K, n 5K is a functional amphiphilic block copolymer with terminal biotin. It combines a 20K hydrophobic PDLLA block with a 5K hydrophilic PEG block specifically for affinity-based functionalization and drug-delivery research.
Key Features and Benefits
- Amphiphilic Block Copolymer: Combines hydrophobic PDLLA with hydrophilic PEG for self-assembly, formulation, and biomaterial development.
- PDLLA MW 20K: Provides a biodegradable hydrophobic block specifically for core formation, structural support, and incorporation of hydrophobic compounds.
- PEG MW 5K: Provides a substantial hydrophilic segment specifically for aqueous compatibility, steric stabilization, and surface presentation.
- Terminal Biotin: Provides a high-affinity recognition site for avidin, streptavidin, and related biotin-binding proteins.
- High-Affinity Recognition: Biotin forms strong, specific noncovalent interactions with avidin and streptavidin.
- Biodegradable PDLLA Block: The PDLLA segment contains hydrolyzable ester linkages that specifically support gradual degradation under appropriate conditions.
- Hydrophilic PEG Segment: PEG supports aqueous compatibility and stabilization of suitable polymer assemblies.
- Functional Polymer Platform: Terminal biotin enables affinity-based modification of micelles, nanoparticles, and related polymer systems.
Applications
- Polymeric Micelles: Supports self-assembled systems with a hydrophobic PDLLA region and hydrophilic PEG interface.
- Nanoparticle Formulation: Supports preparation of PEG-containing polymeric nanoparticles and related delivery systems.
- Avidin-Biotin Binding: Enables high-affinity interactions with avidin, streptavidin, and related biotin-binding proteins.
- Affinity-Based Functionalization: Supports noncovalent attachment of compatible avidin- or streptavidin-containing components.
- Drug Delivery: Supports development of amphiphilic polymer systems for drug-delivery and controlled-release research.
- Bioconjugation: Enables affinity-based association with biotin-binding proteins and compatible functional components.
- Surface Functionalization: Terminal biotin supports affinity-based modification of PEG-presenting polymer assemblies.
- Biomaterial Research: Supports development of functional micelles, nanoparticles, polymer conjugates, 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.
