8-Arm PLGA-COOH, MW 40K is a biodegradable multi-arm PLGA polymer with eight terminal carboxyl groups and an approximate molecular weight of 40 kDa. Its branched structure specifically supports multivalent conjugation, drug delivery, crosslinking, and biomaterial development.
Key Features and Benefits
- 8-Arm Architecture: Creates a branched polymer structure with multiple functional arms.
- Carboxyl Functionalization: Provides terminal carboxylic acid groups for conjugation and further derivatization.
- MW 40K: Supports durable polymer networks and sustained-release formulations.
- Biodegradable: PLGA hydrolyzes into lactic acid and glycolic acid under physiological conditions.
- Multivalent Reactivity: Multiple carboxyl groups support efficient conjugation, crosslinking, and multifunctional modification.
Applications
- Bioconjugation: Activated carboxyl groups couple with amine-containing proteins, peptides, ligands, and other molecules.
- Drug Delivery: Supports biodegradable controlled and sustained-release carrier systems.
- Crosslinking: Forms functional polymer networks through carboxyl-mediated coupling reactions.
- Nanoparticles: Supports the preparation and surface functionalization of biodegradable polymeric nanoparticles.
- Biomaterials: Enables development of scaffolds, coatings, hydrogels, and other biodegradable materials.
Storage and Handling
- Storage: Store at –20 °C in a sealed, dry container.
