Biotin-PEG9-acid

Biotin-PEG9-acid

This product is a high-purity biotinylation reagent with a terminal carboxylic acid connected by a PEG9 spacer for solubility and flexibility.

Key Features and Benefits

• 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.

This product provides a biotin tag and a carboxyl group on a PEG9 spacer, enabling efficient biotinylation and conjugation specifically with improved solubility and reduced steric hindrance.
