Mal-Lys(m-PEG4)-Val-Cit-PAB(m-PEG8)-Exatecan texas red NCCCCCCOC1=CC=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=C1 Purity (HPLC) >= 95%SOLU 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 payload is Exatecan, a highly potent topoisomerase I inhibitor derived from camptothecin, which induces DNA damage by
