Azide-PEG3-Maleimide kit

Azide-PEG3-Maleimide enables simple and efficient incorporation of azido moiety onto antibodies, cysteine-containing peptides and other thiol-containing molecules.


  • Solubility – reagent easily prepared in water-miscible solvents for subsequent dilution into aqueous reaction mixtures
  • Sulfhydryl-reactive – maleimide reacts rapidly with reduced cysteines and other molecules that contain reduced thiols (–SH groups), attaching the DBCO moiety via a stable thioether bond
  • Extended PEG3 Spacer – PEG spacer arm is hydrophilic and provides labeled molecules with greater aqueous solubility compared to reagents having only hydrocarbon spacers
  • Chemoselective – azide and alkyne groups do not react or interfere with other functional groups found in biological samples but conjugate to one another with high efficiency

Azide-PEG3-Maleimide degrades quickly (hours) at room temperature. This product is provided as a two-component easy-to-use kit. Stock solution of Azide-PEG3-Maleimide is prepared with a straightforward mix-and-stir protocol in 30 min.
