Publication number: 20090082225Abstract: This invention is directed to a process for tightly binding nucleic acid to solid phase and corresponding processes for the utilization thereof. Nucleic acid is bound to solid phase matrices exhibiting sufficient hydrophilicity and electropositivity to tightly bind the nucleic acids from a sample. These processes include nucleic acid (double or single stranded DNA and RNA) capture from high volume and/or low concentration specimens, buffer changes, washes, and volume reductions, and enable the interface of solid phase bound nucleic acid with enzyme, hybridization or amplification strategies. The tightly bound nucleic acid may be used, for example, in repeated analyses to confirm results or test additional genes in both research and commercial applications. Further, a method is described for virus extraction, purification, and solid phase amplification from large volume plasma specimens.Type: ApplicationFiled: April 21, 2008Publication date: March 26, 2009Applicant: APPLERA CORPORATIONInventors: John C. GERDES, Jeffery M. Marmaro, Jeffrey T. Ives, Christopher A. Roehl

Patent number: 7087387Abstract: This invention provides a kit comprising a substrate having a surface coated with a solid phase matrix for nucleic acid manipulation. The solid phase matrix exhibits sufficient hydrophilicity and electropositivity to tightly bind the nucleic acids in a sample. The manipulations include nucleic acid (double or single stranded DNA and RNA) capture from high volume and/or low concentration specimens, buffer changes, washes, and volume reductions, and enable the interface of solid phase bound nucleic acid with enzyme, hybridization or amplification strategies. The tightly bound nucleic acid may be used, for example, in repeated analyses to confirm results or test additional genes in both research and commercial applications. Further, a method for virus extraction, purification, and solid phase amplification from large volume plasma specimens is described.Type: GrantFiled: October 21, 2003Date of Patent: August 8, 2006Assignee: Applera CorporationInventors: John C.

Patent number: 6291166Abstract: This invention is directed to a process for irreversibly binding nucleic acid to solid phase and corresponding processes for the utilization thereof. Nucleic acid is bound to solid phase matrixes exhibiting sufficient hydrophilicity and electropositivity to irreversibly bind the nucleic acids from a sample. These processes include nucleic acid (double or single stranded DNA and RNA) capture from high volume:low concentration specimens, buffer changes, washes, and volume reductions, and enable the interface of solid phase bound nucleic acid with enzyme, hybridization or amplification strategies. The invention, solid phase irreversibly bound nucleic acid, may be used, for example, in repeated analyses to confirm results or test additional genes in both research and commercial applications. Further, a method is described for virus extraction, purification, and solid phase amplification from large volume plasma specimens.Type: GrantFiled: April 16, 1998Date of Patent: September 18, 2001Assignee: Xtrana, Inc.Inventors: John C.
