[Description]

Acid-PEG6-SS-PEG6-acid is a homobifunctional cleavable linker. The terminal carboxylic acids can react with primary amines in the presences of activators such as EDC and HATU to form stable amide bonds. The disulfide bonds can be cleaved by using Dithiothreitol (DTT) reagent. PEG6 spacer increase the compound;s solubility.
[Uses]

Bis-(PEG6-acid)-SS is a cleavable 6 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1].
