PEG

Bromo-PEG3-CH2CO2H is a PEG linker containing a bromide group with a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG3)-N-Boc-PEG3-NHS ester is a branched PEGylation linker. The azide group allows for Click Chemistry reactions to take place. The Boc-protected amine can be deprotected under acidic conditions. The NHS ester can react with primary amines. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
