The method for enhanced sensitivity involves carrying out the amplification reaction in the presence of gellan. For instance, the method allows for the production of detectable amounts of PCR amplified DNA from at least 10 fold fewer target molecules than a comparable PCR reaction in absence of gellan.Type: GrantFiled: October 23, 2009Date of Patent: March 26, 2013Assignee: Shin-Etsu Chemical Co. Ltd.Inventor: Richard W. Armentrout

Patent number: RE44596Abstract: The present invention relates to a method for the diagnosis and/or the follow up of the evolution of cancer, which includes the analysis and quantification of over expressed and amplified genes in the plasma/serum of cancer patients or persons suspected to harbor cancer. This is achieved by analyzing together the amount of DNA and RNA of certain genes in the plasma/serum of cancer patients that are the reflection of a gene amplification and/or a gene over expression in comparison to healthy controls.Type: GrantFiled: April 13, 2012Date of Patent: November 12, 2013Assignee: Guardant Health, Inc.Inventors: Maurice Stroun, Philippe Anker
