Polyethylene Glycol (PEGs & PEOs)

m-PEG3-aldehyde is a PEG derivative containing an aldehyde group. Aldehyde is reactive to hydrazide and aminooxy groups which are commonly used in biomolecular probes for labeling and crosslinking carbonyls (oxidized carbohydrates). The hydrophilic

m-PEG3-Ms is a PEG derivative containing a mesyl group. The mesyl group is a good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media.
