Amino-PEG23-acid
This product is a bifunctional PEG23 linker with a terminal primary amine and a carboxylic acid. The long PEG23 spacer provides excellent hydrophilicity, extended flexibility, and wide spacing, making it especially suitable for bioconjugation, drug delivery, and advanced surface engineering.
Key Features and Benefits:
-
Amine Group: Couples efficiently with carboxyls, NHS esters, and electrophiles.
-
Carboxylic Acid Group: Forms stable amide bonds with primary amines.
-
PEG23 Spacer: Provides long-range solubility, flexibility, and reduced steric hindrance.
-
High Purity: Ensures reproducibility in sensitive bioconjugation workflows.
-
Dual Reactivity: Supports orthogonal and multistep conjugation strategies.
Applications:
-
Bioconjugation: Enables precise attachment of proteins, peptides, and biomolecules.
-
Drug Delivery: PEGylated linker improves solubility, stability, and pharmacokinetics.
-
Surface Functionalization: Functionalizes nanoparticles, hydrogels, and polymers.
-
Material Science: Useful for PEGylated scaffolds and biomaterial development.
Storage and Handling:
-
Storage: Store at –20 °C in a dry, light-protected environment.
-
Handling: Use anhydrous solvents (e.g., DMF, DMSO) to preserve amine and acid reactivity.
This product combines a long PEG spacer with dual reactive groups, making it an especially versatile tool for bioconjugation, drug delivery, and advanced synthetic applications.
