Medchemexpress LLC DBCO-PEG6-NHS ester | 96.0% | 737.79 | 5 MG
SDP

DBCO-PEG6-NHS ester is a click chemistry PEG reagent that contains an NHS ester. This NHS ester specifically reacts with primary amines, such as the side chains of lysine residues or aminosilane-coated surfaces, forming covalent bonds efficiently under neutral or slightly alkaline conditions. Additionally, DBCO-PEG6-NHS ester includes a DBCO group, which can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.

  • Reacts specifically with primary amines.
  • Contains a DBCO group for SPAAC with Azide groups.
