PLGA Acid Capped (PLGA-COOH, 75:25), MW 2K is a low-molecular-weight, carboxyl-terminated poly(D,L-lactide-co-glycolide) copolymer. Its 75:25 lactide:glycolide composition and reactive COOH end group specifically support drug delivery, bioconjugation, and functional polymer development.
Key Features and Benefits
- Acid Capped: Provides a terminal carboxylic acid group for conjugation and further functionalization.
- 75:25 PLGA Ratio: Higher lactide content supports controlled degradation and drug release.
- MW 2K: Offers very low molecular weight for especially efficient processing and flexible formulation development.
- Reactive COOH Group: Supports amine coupling after activation with standard carbodiimide chemistry.
- Functionalizable Polymer: Enables attachment of targeting ligands, linkers, peptides, and other functional molecules.
- Biodegradable: PLGA hydrolyzes into lactic acid and glycolic acid under physiological conditions.
Applications
- Drug Delivery: Supports controlled release through biodegradable polymer systems.
- Bioconjugation: Enables attachment of peptides, proteins, targeting ligands, and other amine-containing molecules.
- Nanoparticles: Supports functional PLGA nanoparticles and biodegradable drug carriers.
- Polymer Modification: Provides a reactive COOH group for introducing linkers, ligands, and functional molecules.
- Biomaterials: Supports functional biodegradable matrices, coatings, and other polymer systems.
Storage and Handling
- Storage: Store at –20 °C in a fully sealed container under dry and dark conditions.
- Handling: Protect from moisture, light, and excessive heat to maintain molecular weight and polymer performance.
This product combines very low molecular weight with reactive carboxyl functionality. Its lactide-rich composition specifically supports drug delivery, bioconjugation, polymer modification, and functional biodegradable material development.
