| | MPEG3-NHS Usage And Synthesis |
| Description | m-PEG4-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. | | reaction suitability | reagent type: chemical modification reagent
