Glu-urea-Glu-NHS ester(Cat No.:I043400)is a compound designed for use in biochemical research and drug development. It consists of two glutamic acid (Glu) residues connected via a urea linkage, with an NHS ester group at the terminal. The NHS ester group allows for covalent attachment to primary amines on target molecules, facilitating the conjugation of the compound to proteins, peptides, or other biomolecules. This compound is often used in the development of targeted therapies, as it can selectively modify proteins for applications in drug delivery systems, diagnostics, or protein labeling studies.
