Probing the interaction of the biotin-avidin complex with the relaxivity of biotinylated Gd-DTPA

Org Biomol Chem. 2004 May 7;2(9):1271-3. doi: 10.1039/b402917h. Epub 2004 Apr 6.

Abstract

A biotinylated Gd-DTPA complex is designed to study the biotin-avidin complexation using the longitudinal relaxivity of this new MRI label, which illustrates the use of MRI contrast agents to probe the formation of supramolecular assemblies in water.
