Fmoc-PEG2-NHS ester
This product is a PEG-based linker containing an Fmoc-protected amine, a PEG2 spacer, and an N-hydroxysuccinimide (NHS) ester. It enables efficient amine coupling through the NHS group while offering an orthogonal Fmoc-protected amine for controlled deprotection and further conjugation.
Key Features and Benefits
-
NHS Ester: Couples efficiently with primary amines to form stable amide bonds.
-
Fmoc-Protected Amine: Provides orthogonal reactivity after selective deprotection.
-
PEG2 Spacer: Improves solubility and minimizes steric hindrance.
-
Dual Functionality: Combines immediate amine coupling with protected amine chemistry.
-
High Purity: Ensures reproducibility in synthetic and bioconjugation workflows.
Applications
-
Bioconjugation: Links biomolecules via NHS ester chemistry and protected amine handles.
-
Probe Development: Builds multifunctional probes for diagnostics and imaging.
-
Drug Delivery: Constructs PEGylated scaffolds with orthogonal chemistry.
-
Organic Synthesis: Serves as a versatile intermediate for modular linker design.
Storage and Handling
-
Storage: Keep at –20 °C in a sealed, light- and moisture-protected container.
-
Handling: Use anhydrous solvents such as DMF or DMSO to maintain reactivity.
This product combines amine-reactive NHS chemistry with an Fmoc-protected amine in a PEG2 scaffold, specifically offering a compact and versatile linker for controlled multifunctional conjugation.
