Product Information
| Description | BrCH2CONH-PEG2-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-PEG2-NHS ester; Bromoacetamido-PEG2-C2-NHS ester; 2,5-dioxopyrrolidin-1-yl 3-(2-(2-(2-bromoacetamido)ethoxy)ethoxy)propanoate; 2-Bromo-N-[2-(2-{3-[(2,5-dioxo-1-pyrrolidinyl)oxy]-3-oxopropoxy}ethoxy)ethyl]acetamide; Acetamide, 2-bromo-N-[2-[2-[3-[(2,5-dioxo-1-pyrrolidinyl)oxy]-3-oxopropoxy]ethoxy]ethyl]- |
