Propargy-Gly(m-PEG4)-Gly-Gly-Phe-Gly-PAB-PNP biotin Product Name 2-[4-(carboxymethyl)piperazin-1-yl]acetic acid dihydrochlorideSOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. In this product, a Propargyl Gly(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The propargyl functional group is widely employed in click chemistry to undergo selective cycloaddition with azides. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as PEG, amine containing
