Patent number: 11457899Abstract: In order to address an inability to separate portions of a sample and/or substance, in some embodiments, methods and apparatuses for separating components and/or portions of a sample are provided. For example, a sample collection container may comprise two areas within the container, one which is configured to contain a first volume of the sample, and one which is configured to contain a second volume of the sample. A float device may be configured to seal the portion of the container collecting the first volume from the portion of the container collecting the second volume, after the former portion of the container has been filled. The sample collection container may further comprise a top cap configured to further seal the two portions of the container, and to prevent leakage and/or spilling of the sample from the sample collection container.Type: GrantFiled: September 30, 2015Date of Patent: October 4, 2022Assignee: Exosome Diagnostics, Inc.Inventors: Johan Skog, Bill Tisel, Joseph Baker

Patent number: 11396676Abstract: The invention provides a series of steps that prepare nucleic acids (RNA and/or DNA) isolated from extracellular vesicles for sequencing. This enables a wide diversity of RNAs and/or DNAs, to be efficiently detected. These can then be used to identify various attributes such as gene expression, alternative splicing, and the detection of both somatic and germline mutations including single nucleotide variants (SNV) and structural variations (insertions/deletions, fusions, inversions).Type: GrantFiled: October 23, 2017Date of Patent: July 26, 2022Assignee: Exosome Diagnostics, Inc.Inventors: Johan Skog, Sudipto Chakrabortty, Dalin Chan, Michael Valentino, Vasisht Tadigotla, Robert Kitchen, Dominik Grimm, Wei Yu

Publication number: 20170114389Abstract: The present invention is partly based on the discovery that adverse factors can prevent an effective extraction of nucleic acids from a biological sample and that novel and unexpected agents and steps may be used to mitigate or remove the adverse factors, thereby dramatically improving the quality of the extracted nucleic acids. As such, one aspect of this invention is a novel method for extracting high quality nucleic acids from a biological sample. The high quality extractions obtained by the novel methods described herein are characterized by high yield and high integrity, making the extracted nucleic acids useful for various applications in which high quality nucleic acid extractions are preferred, e.g., a diagnosis, prognosis or therapy evaluation for a medical condition.Type: ApplicationFiled: December 9, 2016Publication date: April 27, 2017Applicant: THE GENERAL HOSPITAL CORPORATIONInventors: Leileata M.

Patent number: 7459153Abstract: Adenovirus types 11p and 4p show a higher binding affinity and infectivity than type 5 for endothelial and carcinoma cell lines. Adenovirus type 11p shows a stronger binding to cells for neural origin, such as glioblastoma, neuroblastoma and medulloblastoma. The fact that adenovirus type 11 has a comparatively low prevalence in society, together with its high affinity and infectivity, makes it very suitable for use in gene therapy.Type: GrantFiled: January 4, 2002Date of Patent: December 2, 2008Inventors: Göran Wadell, Ya-fang Mei, Anna Segerman, Johan Skog, Kristina Lindman
