Biotin-PEG2-CH2-aldehyde

Biotin-PEG2-CH2-aldehyde

This product is a biotinylated PEG linker with an aldehyde reactive group. The PEG2 spacer improves solubility and provides flexibility. This dual-functional design specifically supports bioconjugation, labeling, and probe development in biological and material research.

Key Features and Benefits

• Biotin Moiety: Enables high-affinity binding to streptavidin and avidin systems.

• Aldehyde Group: Reacts with amines or hydrazides for stable conjugation.

• PEG2 Spacer: Enhances solubility while maintaining compact structure.

• Dual Functionality: Combines biotin binding with aldehyde coupling.

• High Purity: Ensures reproducibility and consistency in sensitive applications.

Applications

• Bioconjugation: Links biotinylated molecules to proteins, peptides, or nanoparticles.

• Probe Development: Builds aldehyde-reactive biotinylated probes for imaging and diagnostics.

• Affinity Studies: Supports avidin–biotin binding assays and pull-down experiments.

• Material Science: Functionalizes surfaces and polymers with biotin and aldehyde chemistry.

Storage and Handling

• Storage: Keep at –20 °C in a sealed, light- and moisture-protected container.

• Handling: Use anhydrous solvents (e.g., DMF, DMSO); avoid prolonged exposure to moisture.

This product combines biotin–streptavidin affinity with aldehyde conjugation chemistry in a compact PEG2 framework, providing an especially versatile tool for advanced bioconjugation and assay development.
