Description and Uses

Bis-PEG2-NHS ester is a PEG linker containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

Bis-PEG2-NHS ester is a nonclaevable 2-unit PEG linker for antibody-agent-conjugation (ADC).
