20080227212 | PROCESS FOR IDENTIFYING EXISTENCE OF SINGLE NUCLEOTIDE POLYMORPHISM WITHOUT DNA SEQUENCING - A process for detecting the presence of a mutation in an oligonucleotide strand such as a DNA strand from a gene without the need for DNA sequencing is provided. The inventive process provides a rapid pre-test to screen for the presence or absence of a mutation in a target gene of a subject to determine whether laborious sequencing protocols are required to further characterize a mutation. The inventive process provides a rapid screening protocol for identifying and detecting a genetic mutation in a patient who presents with a disease | 09-18-2008 |
20080241836 | PROCESS FOR SELF-ASSEMBLY OF STRUCTURES IN A LIQUID - A process and apparatus for self-assembling a number of elements and determining their sequence is provided. In the field of DNA analysis, an iterative process is disclosed wherein an apparatus with a set of reaction chambers in which a species of recognition element nucleotides are differentially added and subjected to a polymerization reaction allows recognition of which species is next in sequence on a template strand by the effect that synthesis has on a detecting template as measured by a detector in a detection area. Stepwise addition of the identified species then determines if an element repeat exists. The process is repeated until the entire structure is complete and the sequence identified. | 10-02-2008 |

20090286694 | NUCLEIC ACID ARRAY WITH RELEASEABLE NUCLEIC ACID PROBES - A process is provided for identifying a complementary target nucleic acid. The process includes the hybridization of a nucleic acid probe to a carrier to form a nucleic acid probe-carrier complex. The complex is placed in a compartment bounded by a media permeable to the nucleic acid probe and exclusive of both the carrier and the complex. The complex is then denatured, with the nucleic acid probe transported through the media and into contact with the target nucleic acid. The nucleic acid probe hybridizes to the complementary target nucleic acid to yield a probe-target double stranded complex. A non-complementary nucleic acid probe, independent probe-target complex is returned to the compartment and given an opportunity to rehybridize to the carrier. A determination as to whether at least one of the complementary target nucleic acid or the carrier is present as a complex provides information as to probe sequences complementary to the target nucleic acid. | 11-19-2009 |
20100056388 | NUCLEIC ACID ARRAY HAVING FIXED NUCLEIC ACID ANTI-PROBES AND COMPLEMENTARY FREE NUCLEIC ACID PROBES - A process for identifying a complementary nucleic acid probe to a target nucleic acid involves forming an array of spots where each spot of the array has an immobilized nucleic acid anti-probe to which is hybridized a nucleic acid probe. The array of the anti-probe-probe complex is denatured. The nucleic acid probes are then moved into a target chamber that includes a target nucleic acid. Hybridization conditions are established to form double-stranded complexation between the target nucleic acid and nucleic acid probes in instances where the target nucleic acid has a sequence complementary. The nucleic acid probes noncomplementary to the target nucleic acid are allowed to rehybridize with anti-probes. Determining whether the anti-probe spots exposed to nucleic acid probes noncomplementary to the target nucleic acid are single stranded after exposure to noncomplementary nucleic acid probes provides information as to target nucleic acid sequence. | 03-04-2010 |
20100108621 | SELF-CONTAINED PARTICLE SEPARATOR DEVICE - A concentrator of particles dissolved or suspended in a liquid includes a top surface having a hole array therethrough and a bottom surface fused to the top surface to define an intermediate volume accessed only through the hole array. A concentrator of particles dissolved or suspended in a liquid is also provided that has an inner channel and an exterior surface and a tube having a hole array providing liquid communication between the inner channel and the exterior surface. A liquid-impermeable sheath surrounds the hole array and forms a seal to the exterior surface to define a volume between said sheath and the exterior surface. A process for concentrating particles from a liquid with these concentrators is also provided. | 05-06-2010 |

20100240119 | MICROSEPARATION STRUCTURE AND DEVICES FORMED THEREWITH - A microseparation structure is provided that includes a top surface defining a first chamber. A second chamber is provided that is in fluid communication with the first chamber and characterized by a volume less than the volume of the first chamber. At least one hole extends in fluid communication with the second chamber to transmit fluids into a capillary draw void volume filled with a capillary draw-inducing agent such that liquid placed in the first chamber is drawn through the second chamber and through the hole to the capillary draw void volume filled with capillary draw-inducing agent. Particles of interest within the liquid are unable to pass into the hole and are therefore isolated within the second chamber. This structure is amenable to forming into a compact chromatographic filtration media made up of multiple such structures that is well suited for sealed testing for diseases such as malaria. | 09-23-2010 |
