Please contact us at firstname.lastname@example.org to place an order for (NH2)3-4ARMPEG-COOH (4arm PEG, 1arm-COOH, 3arm-NH2)
(NH2)3-4ARMPEG-COOH (4arm PEG, 1arm-COOH, 3arm-NH2) with various MW from JenKem Technology is a high quality 4arm heterobifunctional PEG product. JenKem Technology’s patented multi-arm heterofunctional PEG derivatives are designed as linkers for Antibody-Drug Conjugates (ADCs), as they facilitate the coupling of high ratios of drug molecules 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.
Multi-arm Heterofunctional PEG products with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at email@example.com about pricing and availability.
Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
