Amino-PEG6-bis-PEG5-azide is a branched PEG linker that offers multiple conjugation points for enhanced drug loading in ADC development. The terminal amino group readily reacts with carboxylic acids, activated NHS esters, and carbonyl groups (aldehydes and ketones), while the two azide groups enable efficient click chemistry conjugation with DBCO, BCN, or alkynes. The hydrophilic PEG spacers ensure excellent water solubility, further improving biocompatibility and performance. Reagent grade, for research use only.
