摘要 |
<p>The present invention concerns the use of a protein capable of spontaneously forming an isopeptide bond for the development of a peptide tag and binding partner pair wherein said peptide tag and binding partner are capable of covalently binding to each other via an isopeptide bond. The invention also provides a method for developing a peptide tag and binding partner pair which are capable of covalently binding to each other based on a protein which is capable of spontaneously forming an isopeptide bond. Additionally provided are peptide tag and binding partner pairs which are obtainable from isopeptide proteins. Further, specifically developed peptide tags and binding partners are encompassed, together with nucleic acid molecules and vectors which encode those peptides or proteins.</p> |
