Desthiobiotin-PEG3-azide is a ligand that binds to the nucleotide binding site of proteins. It has been shown to bind to nucleophilic sites on proteins, such as phosphotyrosine. The covalent bond formed between Desthiobiotin-PEG3-azide and protein is stable and biocompatible, which means it does not harm cells in culture. Desthiobiotin-PEG3-azide can be used for chemical proteomics by modifying the protein with this ligand.
