Polyethylene Glycol (PEGs & PEOs)

m-PEG-NHS ester, MW1K is a PEG derivative 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

m-PEG-NHS ester, MW5k is a PEG derivative 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

m-PEG-NHS ester, MW 10K is a PEG derivative 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

m-PEG-NHS ester, MW 20K is a PEG derivative 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

m-PEG-Nitrophenyl Carbonate, MW 2K is a PEG derivative that contains a nitrophenyl carbonate (NPC). The NPC group is reactive towards the amino group of lysine by means of stable urethane linkages. The PEG linker enhances the water solubility
