Mal-PEG2-VCP-Eribulin（Cat No.:I018595）, also known as Mal-PEG2-Val-Cit-PAB-Eribulin, is a complex molecule that serves as a linker for the synthesis of antibody-drug conjugates (ADCs). It consists of a maleimide (Mal) group, two units of polyethylene glycol (PEG2), a valine-citrulline peptide (VCP) linker, and the cytotoxic agent eribulin. This linker is designed to facilitate the conjugation of eribulin to antibodies, enabling targeted delivery of the cytotoxic drug to specific cells or tissues.
