JenKem Technology provides high purity activated heterobifunctional PEGs for Antibody-Drug Conjugates (ADCs). Incorporation of PEG linkers between the antibody and payload can influence the properties1 of the ADCs.PEG Linkers for ADCs

– Modulate the physicochemical properties, such as balance the payloads’ hydrophobicity, improve solubility, increase DAR, and reduce aggregation
– Modify the Pharmacodynamic properties, such as increase the rate of payload release and increase invitro cytotoxicity
– Optimize the pharmacokinetic properties, such as clearance, half-life, and biodistribution

JenKem Technology provides a variety of PEG linkers to help with your ADC-related projects. JenKem Technology’s patented multi-arm heterofunctional PEG derivatives are designed as linkers for ADCs, as they facilitate the coupling of high ratios of drug molecules per antibody, thus increasing Drug-to-antibody ratio (DAR). Examples include but are not limited to 4ARM-PEG-(NH2)3-COOH, 4ARM-PEG-(MAL)3-NHS, 8ARM-PEG-(NH2)7-COOH, or 8ARM-PEG-(MAL)7-NHS.

Additionally, JenKem Technology offers many monodisperse PEG linkers for ADCs with high purity, in large commercial scale, in both GMP and non-GMP grade, some examples listed below.
