PLGA Ester Capped (85:15), MW 70K is a biodegradable copolymer with an 85:15 lactide:glycolide ratio, ester end groups, and an approximate molecular weight of 70 kDa. Its lactide-rich composition specifically supports sustained drug delivery and durable biomaterial systems.
Key Features and Benefits
- Ester Capped: Provides ester end groups that reduce terminal carboxyl functionality.
- 85:15 PLGA Ratio: High lactide content supports slower water uptake and extended degradation compared with glycolide-rich PLGA compositions.
- MW 70K: Balances polymer processability with durable matrix formation and sustained-release performance.
- Biodegradable: PLGA hydrolyzes into lactic acid and glycolic acid under physiological conditions.
- Versatile Polymer: Supports particles, films, implants, scaffolds, and other biodegradable delivery systems.
Applications
- Sustained Drug Delivery: Extends drug release through biodegradable polymer matrices.
- Long-Acting Formulations: Supports development of implants, depots, and other prolonged-release systems.\
- Microparticles: Forms biodegradable microspheres and related drug-loaded particles.
- Biomaterials: Supports scaffolds, films, coatings, and durable biodegradable matrices.
- Formulation Research: Enables studies of polymer degradation, drug release, and lactide-rich PLGA performance.
Storage and Handling
- Storage: Store at –20 °C in a sealed, dry container.
- Handling: Protect from moisture and excessive heat to limit premature hydrolysis and polymer degradation.
PLGA Ester Capped (85:15), MW 70K combines ester end groups, lactide-rich composition, and intermediate molecular weight to specifically support sustained drug delivery, long-acting formulations, polymer matrices, and advanced biomaterial development.
