Publication number: 20150037797Abstract: The invention relates to a method of detecting nucleic acid molecules by immunoassay detection. Detection of a specific nucleic acid molecule of interest is achieved by using a nucleic acid probe in solution which hybridizes in solution to the nucleic acid molecule of interest. Immunoassay detection is achieved by using an antibody specific for the hybrid formed by hybridization of the nucleic acid probe to the nucleic acid molecule of interest.Type: ApplicationFiled: March 8, 2013Publication date: February 5, 2015Applicants: SIEMENS HEALTHCARE DIAGNOSTICS INC, SIEMENS HEALTHCARE DIAGNOSTICS PRODUCTS GMBHInventors: Andreas Kappel, Andreas Keller, Cord Friedrich Stahler, Ian Wright, Linda Marie Anderson-Mauser, William Bedzyk, Herbert Schwarz, Michaela Wicke

Publication number: 20140308751Abstract: Methods include adjusting a contribution of one of two analyte homologs to an amount of signal obtained in an assay for determining a total amount of the two analyte homologs in a sample. A non-assay receptor is employed that has a greater binding affinity for whichever of the two analyte homologs whose contribution to the amount of signal is to be adjusted. An amount of the non-assay receptor is sufficient to achieve an adjustment of the contribution of the analyte homolog to the signal. The assay for determining the total amount of the two analyte homologs is conducted where the assay utilizes at least one assay antibody.Type: ApplicationFiled: April 12, 2013Publication date: October 16, 2014Applicant: Siemens Healthcare Diagnostics Inc.Inventors: Tie Q. Wei, William Bedzyk, Elsa Garcia

Publication number: 20080039656Abstract: The present invention relates to immobilized procainamide analogs, as well as to a method of making immobilized procainamide analogs. These immobilized analogs are prepared by activating the carboxyl group on a substituted p-benzoic acid derivative toward nucleophilic attack; reacting the activated benzoic acid derivative with a polyamine to produce the benzoic acid derivative of Formula 3: and binding the benzoic acid derivative of Formula 3 to a latex polymer having functional groups that react with aliphatic amino groups. A method of conducting an immunoassay using the immobilized procainamide analog Formula 3 is described, comprising the steps of preparing a solution comprising said immobilized procainamide analog; adding a sample suspected of containing procainamide to said solution; adding an anti-procainamide antibody to said solution and observing the rate of increase in solution turbidity following antibody addition.Type: ApplicationFiled: August 28, 2007Publication date: February 14, 2008Applicant: DADE BEHRING INC.Inventors: Victor Chu, Zhu Teng, Steve Goss, Ronald Edwards, Kelle Garvey, Timothy Gorzynski, William Bedzyk
