Product Information

Description	t-Boc-N-amido-PEG3-NHS ester is a PEG linker containing NHS ester and Boc-protected amine moieties. The Boc group can be deprotected under mildly acidic conditions to form a free amine. 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.
Synonyms	Boc-NH-PEG3-NHS ester; 2,5-Dioxopyrrolidin-1-yl 2,2-dimethyl-4-oxo-3,8,11,14-tetraoxa-5-azaheptadecan-17-oate; BocNH-PEG3-CH2COONHS; 2-Methyl-2-propanyl {2-[2-(2-{3-[(2,5-dioxo-1-pyrrolidinyl)oxy]-3-oxopropoxy}ethoxy)ethoxy]ethyl}carbamate; Carbamic acid, N-[2-[2-[2-[3-[(2,5-dioxo-1-pyrrolidinyl)oxy]-3-oxopropoxy]ethoxy]ethoxy]ethyl]-, 1,1-dimethylethyl ester
