    AI Overview
    N3-PEG5-Mal (Azide-PEG5-maleimide) is
    a heterobifunctional, monodispersed PEG linker (five ethylene glycol units) containing an azide group and a maleimide group . It is widely used in click chemistry for conjugation, enabling the selective linking of molecules via azide-alkyne cycloaddition and thiol-reactive maleimide chemistry for bioconjugation, drug delivery, and surface modification.
    Key Features and Applications:
    • Structure: Azide (
      N 3 cap N sub 3
      𝑁 3
      ) - PEG spacer (
      P E G 5 cap P cap E cap G sub 5
      𝑃 𝐸 𝐺 5
      ) - Maleimide (
      M a l cap M a l
      𝑀 𝑎 𝑙
      ).
    • Reactivity: The azide group reacts with alkyne groups (click chemistry), while the maleimide group reacts with sulfhydryl (thiol, -SH) groups.
    • Uses: Ideal for site-specific labeling, developing antibody-drug conjugates (ADCs), PEGylation of proteins/peptides, and developing crosslinkers.
    • Storage: Should be stored at low temperatures (
      − 2 0 ∘
      𝐶
      ), under inert gas (nitrogen or argon), and protected from light.
    • Properties: Provides a precise, well-defined length (monodispersed) for consistent results.
    This reagent is specifically useful for applications requiring the bridging of two different molecules, such as a protein (via cysteine/thiol) and a drug or probe (via an alkyne).
