m-PEG8-NHS ester Chemical Properties,Uses,Production
Description
m-PEG8-NHS ester is a PEG linker containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media.
Uses
m-PEG8-NHS ester is a non-cleavable 8 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs).
reaction suitability
reagent type: chemical modification reagent
reagent type: cross-linking reagent
reactivity: amine reactive
in vitro
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
