APN-C3-Biotin

APN-C3-Biotin (CAS: 2170240-97-6) is a heterobifunctional linker that combines an APN (4-azidophenyl) moiety with biotin for APN-cysteine conjugates.

Key Features:

• Selective Reactivity: The APN group exhibits high chemoselectivity toward cysteine residues, facilitating targeted conjugation.
• Biotin Tagging: The biotin component allows for easy detection and purification using streptavidin-based methods.
• Stability: APN-cysteine conjugates demonstrate superior stability in aqueous media, human plasma, and living cells, enhancing their utility in various biological contexts.

Applications:

• Protein Labeling: Used for tagging proteins at specific cysteine residues.
• Bioconjugation Studies: In research involving protein-protein interactions and cellular processes.
• Diagnostic Assays: Utilized in assays requiring biotin-streptavidin interactions.
