What is Mal-PEG2-acid?
Description
Mal-PEG2-acid is a PEG linker containing a maleimide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
Biological Activity
Mal-PEG2-acid is a non-cleavable ADC linker for the synthesis of antibody-drug conjugates (ADCs). It can bind to Tubulysin (HY-128914) and its cytotoxic derivatives activity. It can also be used as a PROTAC linker for PROTAC synthesis.
in vitro
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
