NHS-PEG-COOH is a heterobifunctional PEG linker with an N-hydroxysuccinimide (NHS) ester group and a carboxyl group (-COOH). The NHS ester group of NHS-PEG-COOH reacts selectively with primary amines to form stable amide bonds, facilitating the conjugation of PEG chains to biomolecules such as proteins, peptides, or amino-modified surfaces. The carboxyl group in NHS-PEG-COOH enables additional functionalization, including conjugation with amine-containing molecules or the immobilization of biomolecules onto surfaces.
