Mal-amido-PEG10-C2-NHS ester is a nonclaevable ADC linker containing a maleimide group and an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules[1][2]
Amino-PEG6-amido-bis-PEG5-N3 is a cleavable 11 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Amino-PEG6-amido-bis-PEG5-N3 is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. Strain-promoted alkyne-azide cycloaddition (SPAAC) can also occur with molecules containing DBCO or BCN groups.
