5-FAM-PEG3-DBCO is a fluorescent linker combining 5-FAM (5-carboxyfluorescein) with DBCO (Dibenzocyclooctyne) via a PEG3 spacer. It allows copper-free click chemistry with azide-functionalized biomolecules, providing bright fluorescence for imaging applications without the need for toxic catalysts.
Applications:
- Fluorescent Labeling: 5-FAM provides bright, stable fluorescence for biomolecule tagging.
- Copper-Free Click Chemistry: DBCO enables rapid, biocompatible conjugation with azide groups.
- Molecular Imaging: Suitable for live-cell imaging and fluorescence-based assays.
FAM-PEG3-DBCO is widely used in molecular imaging, targeted labeling, and bioassays requiring safe, efficient fluorescent conjugation.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
