Heterobifunctional PEG refers to PEG derivatives containing different functional groups at both ends and is often used as a cross-linking agent or used as a bridge between two different chemical entities.
The PEG main chain part of Biochempeg's heterobifunctional PEG provides end groups with water solubility, biocompatibility and flexibility, and can be used in the development and application of antibody-drug conjugates (ADC's).
The following general structure of heterobifunctional PEG derivatives are available at Biochempeg. You can feel free to click the catalog number to see purity specifications and more information.
