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.
