Biotin-PEG2-NHS ester is PEG derivative containing a biotin group and an NHS ester group. The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups to form stable amide bonds. The PEG2 spacer provides solubility and flexibility to the molecule, allowing for enhanced accessibility to the target molecules. It is a valuable tool for researchers in the fields of chemical biology, drug discovery, and biomedical engineering.
