Bis-PEG4-PFP ester
This product is a homobifunctional PEG linker containing two pentafluorophenyl (PFP) ester groups connected by a PEG4 spacer. It specifically enables efficient crosslinking of amine-containing molecules, offering solubility, flexibility, and strong reactivity for bioconjugation and materials modification.
Key Features and Benefits
-
Dual PFP Esters: React efficiently with primary amines to form stable amide bonds.
-
PEG4 Spacer: Provides solubility, flexibility, and moderate chain length.
-
Homobifunctional Design: Enables symmetric crosslinking of biomolecules or polymers.
-
High Reactivity: PFP esters show enhanced stability and reactivity compared to NHS esters.
-
High Purity: Ensures reproducibility in sensitive workflows.
Applications
-
Bioconjugation: Crosslinks proteins, peptides, or small molecules via amine coupling.
-
Probe Development: Builds multifunctional probes for imaging and diagnostics.
-
Drug Delivery: Provides PEG scaffolds with reactive amine-coupling handles.
-
Material Science: Functionalizes nanoparticles, surfaces, and polymers with PEGylation.
Storage and Handling
-
Storage: Store at –20 °C in a sealed, light- and moisture-protected container.
-
Handling: Use anhydrous solvents such as DMF or DMSO; avoid prolonged exposure to moisture.
