-
Biotin Moiety – Enables high-affinity binding to streptavidin and avidin.
-
Carboxylic Acid Group – Reactive site for amide bond formation with primary amines.
-
PEG9 Spacer – Enhances solubility, reduces steric hindrance, and improves accessibility in conjugates.
-
High Purity – Suitable for bioconjugation, assay development, and drug delivery.
Applications
-
Biotinylation of proteins, peptides, or antibodies
-
Amide coupling for probe and surface functionalization
-
Linker for drug delivery systems and diagnostics
-
Enabling flexible spacing in avidin–biotin capture systems
Handling
-
Storage: Store at –20 °C, dry, and protected from light.
-
Use: Dissolve in anhydrous solvents (e.g., DMF, DMSO). Avoid repeated freeze–thaw cycles.
