Bis-PEG1-NHS ester Chemical Properties, Uses, Production

Description

Bis-PEG1-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.

Uses

Bis-PEG1-NHS ester is a nonclaevable 1-unit PEG linker for antibody-agent-conjugation (ADC).

IC 50
