Biotin-PEG6-Hydrazide
This product is a high-purity biotinylation reagent with a hydrazide group for aldehyde and ketone coupling, specifically connected by a PEG6 spacer for solubility and flexibility.
Key Features and Benefits
-
Biotin Moiety – Enables strong, specific binding to streptavidin and avidin.
-
Hydrazide Group – Reacts with aldehydes and ketones to form stable hydrazone linkages.
-
PEG6 Spacer – Enhances solubility, reduces steric hindrance, and improves conjugate accessibility.
-
High Purity – Suitable for bioconjugation, labeling, and drug delivery workflows.
Applications
-
Biotinylation of aldehyde- or ketone-modified biomolecules
-
Formation of hydrazone linkages in protein and antibody conjugation
-
Probe and diagnostic assay development
-
Linker for drug delivery and biomolecule immobilization
Storage & Handling
-
Storage: Store at –20 °C, dry, and protected from light.
-
Handling: Dissolve in anhydrous solvents (e.g., DMF, DMSO). Avoid repeated freeze–thaw cycles.
This product provides a biotin tag and a hydrazide group on a PEG6 spacer, enabling efficient biotinylation of aldehyde- or ketone-functionalized biomolecules specifically with improved solubility and reduced steric hindrance.
