QTL Biosystems Announces Broad Patent Coverage for the Fluorescent Polymer-QTL Approach to Biosensing
The patented QTL bioconjugate enables quantitative detection of a diverse range of targets such as enzymes, small molecule ligands, proteins including antibodies and antibody fragments, and DNA.
The property-altering component of the QTL bioconjugate covers a range of materials ranging from fluorescent dyes to metal complexes and covers electron donors and acceptors as well as "energy transferring moieties." The claims granted also extend the original QTL sensing approach to systems using polymer superquenching on solid supports. This patent broadens the range of coverage obtained in University of California/Los Alamos National Laboratory patent US 6,589,731, issued July 8, 2003 and licensed exclusively to QTL.
"These two issued patents, together with a number of pending patent applications, provide a strong technology foundation for the QTL LightSpeed(TM) platform," stated David Whitten, co-founder and Chief Science Officer for QTL Biosystems.
