Bis-PEG5-acetic acid
This product is a symmetric PEG-based linker with two terminal carboxylic acid groups separated by a PEG5 spacer. The dual acids enable efficient amide coupling, while the PEG chain improves solubility, flexibility, and spacing for bioconjugation and material applications.
Key Features and Benefits:
-
Dual Carboxylic Acids: Facilitate stable amide bond formation with amines.
-
PEG5 Spacer: Enhances solubility, hydrophilicity, and steric accessibility.
-
Symmetric Design: Supports dual-site conjugation or surface anchoring.
-
High Purity: Provides reproducibility in conjugation and material workflows.
-
Versatile Use: Suitable for protein modification, surface functionalization, and advanced materials.
Applications:
-
Bioconjugation: Couples biomolecules or ligands via dual carboxyl groups.
-
Drug Delivery: PEGylated scaffold improves solubility and stability of therapeutic constructs.
-
Surface Functionalization: Attaches to nanoparticles, polymers, or biosensors.
-
Material Science: Useful in coatings, scaffolds, and polymer engineering.
Storage and Handling:
-
Storage: Store at –20 °C in a tightly sealed, moisture-protected container.
-
Handling: Use anhydrous solvents (e.g., DMF, DMSO) to maintain acid reactivity.
This product combines dual carboxyl groups with a hydrophilic PEG5 chain, making it an especially versatile tool for conjugation, drug delivery, and material design.
