Fmoc-Val-Cit-PAB(m-PEG8) 4' 376 SMILES OC(=O)C1CCN(CC1)C1=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to increase aqueous solubility. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as PEG, amine containing groups, or polysarcosine (PSAR), to enhance aqueous solubility. Solubility and physicochemical properties can be finely tuned
