Product Information

Description	t-Boc-N-amido-PEG12-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	BocNH-PEG12-CH2CH2COONHS; Boc-N-PEG12-C2-NHS ester; 2,5-dioxopyrrolidin-1-yl 2,2-dimethyl-4-oxo-3,8,11,14,17,20,23,26,29,32,35,38,41-tridecaoxa-5-azatetratetracontan-44-oate
