Patent number: 7033613Abstract: Using a gene recombination technique, a glutamic acid and an aspartic acid positioned in a channel of apoferritin are substituted with serine having a small size and no charges.

Publication number: 20040241096Abstract: The invention features methods of detecting enzymatic activity (e.g., in a magnetic resonance image). In general, the methods include: (1) providing a monomeric substrate (e.g., a substrate that is polymerizable in the presence of an enzyme or as a result of an enzyme-catalyzed reaction), having the generic structure X-Y-Z, where X includes a chelator moiety having a chelated paramagnetic or superparamagnetic metal atom or ion, Y includes a linker moiety (e.g., to provide a covalent or non-covalent chemical bond or bonds between X and Z), and Z includes a polymerizing moiety; (2) contacting the substrate with a target tissue, wherein the substrate undergoes polymerization to form a paramagnetic or superparamagnetic polymer, the polymerization being catalyzed by an enzyme in an extracellular matrix or bound to the surfaces of cells of the target tissue; and (3) detecting an increase in relaxivity for the polymer relative to an equivalent amount of unpolymerized substrate.Type: ApplicationFiled: April 30, 2004Publication date: December 2, 2004Applicant: The General Hospital Corporation, a Massachusetts corporationInventors: Alexei Bogdanov, Ralph Weissleder
