Product Information

Description	BrCH2CONH-PEG11-NHS ester is a PEG linker containing a bromide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
Synonyms	Bromoacetamido-PEG11-C2-NHS ester; Bromoacetamido-PEG11-NHS ester; 2,5-dioxopyrrolidin-1-yl 1-bromo-2-oxo-6,9,12,15,18,21,24,27,30,33,36-undecaoxa-3-azanonatriacontan-39-oate
