Heterobifunctional PEGs

Nanosoft Polymers (NSP) offers high quality heterobifunctional PEGs with high purity and low polydispersity.

NSP’s heterobifunctional PEG derivatives are generally employed as crosslinking agents or as spacers between two different chemical entities. The PEG chain in the heterobifunctional PEG derivatives provides water solubility, biocompatibility, and flexibility to the linker. Applications are especially geared towards the development of antibody drug conjugates. Heterobifunctional PEG derivatives have the following general structure:

X―PEG―Y

where X and Y are two different functional or reactive groups.
