<p>There are provided multifunctional chemical reagents useful in cross-linking proteins but having the capability of leaving two or more reaction sites available for further chemical reactions, after completion of the cross-linking process. These reagents can be broadly defined as aromatic compounds comprising an aromatic nucleus including but not limited to phenyl, biphenyl, naphthyl and binaphthyl (as herein defined), with at least four independently selected electronegative substituent groups bonded directly or indirectly to the aromatic nucleus.</p> |
