Aminoethyl-SS-propionic acid

Aminoethyl-SS-propionic acid is a bifunctional crosslinker that can couple with carboxylic acid-activated reagents through amino groups or directly react with sulfhydryl groups (-SH) to achieve directional crosslinking of biomolecules^[1]. Aminoethyl-SS-propionic acid is a cleavable ADC linker that can be used to synthesize antibody-drug conjugates (ADCs)^[2]. Aminoethyl-SS-propionic acid contains a disulfide bond and a terminal amine. The disulfide bond can be cleaved using dithiothreitol (DTT) reagent, and the terminal amine can react with carboxylic acids, activated NHS esters, and other carbonyl compounds^[3]. Aminoethyl-SS-propionic acid can be used in the development of targeted drug delivery and controlled release systems^[4].
