JenKem Technology’s 8arm heterofunctional PEG Derivatives are designed as linkers for Antibody-Drug Conjugates (ADCs), as they facilitate the coupling of high ratios of drug molecule per antibody. ADCs conjugated via multiarm PEGs deliver a higher concentration of drugs to targets for each antibody-antigen interaction, and exhibit improved solubility and PK/PD profile. JenKem Technology’s 8arm (hexaglycerol core) and 8arm (TP, or tripentaerythritol core) heterobifunctional PEG products with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis.
