Mal-PEG(4)-Val-Cit-PAB-PNP is a PEGylated peptide that consists of a PEG (polyethylene glycol) chain linked to a peptide sequence. The PEG moiety provides protection and stability to the peptide, allowing for improved pharmacokinetic properties and prolonged circulation time in the body. This product is commonly used in drug delivery systems and as a tool in biochemical research. The maleimide group on the PEG allows for easy conjugation with thiol-containing molecules, making it highly versatile for various applications. With its unique characteristics, Mal-PEG(4)-Val-Cit-PAB-PNP offers researchers and pharmaceutical companies an efficient solution for enhancing the efficacy and bioavailability of peptides.

Mal-PEG4-Val-Cit-PAB-PNP is a cleavable 4-unit polyethylene glycol (PEG) linker employed in the synthesis of antibody-drug conjugates (ADCs)[1].
