Mal-Lys(m-PEG4)-Val-Cit-PAB(m-PEG8)-PNP Size:100mg Product Name 2-[4-(carboxymethyl)piperazin-1-yl]acetic acid dihydrochlorideSOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a Mal Lys(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. Additionally, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The PNP (para nitrophenyl) moiety serves as an activating leaving group, enabling efficient and selective conjugation of the payload
