摘要:
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.

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
摘要:
Broadband output high power pulsed flash lamps are useful in many applications, and when specifically optimized, can become an excellent source of ultraviolet (UV) light, which is particularly useful for photo-chemically-induced materials processing applications. Multiple factors involved with the production of high-energy light pulses can in certain cases adversely affect the ultraviolet lamp operation, thereby resulting in the development of micro cracks in lamp envelopes and subsequent limitation in lamp lifetime. Similar factors can be responsible for an increased absorption of UV radiation by lamp components and degradation of lamp efficiency. This invention describes new pulsed flash lamp designs that enable a new generation of high power and performance as required by, for example, many large-scale photo-processing applications. This invention uniquely and advantageously mitigates the development of micro-cracks and failure, and produces dramatically improved electrical efficiency, stability of lamp optical characteristics, and service lifetime.

Compositions, methods, apparatuses, kits, and combinations are described for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. The compositions useful in the present disclosure include a décor product that is formulated to be applied and affixed to a surface. If desired, the décor product may be substantially removed from the surface before being affixed thereto. If a user desires to remove the décor product, the décor product is formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the décor product to the surface in a permanent or semi-permanent manner, the décor product may be affixed to the surface by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical. The décor product may also be utilized in the form of a kit or in conjunction with a design device, such as a stencil, to control the application of the décor product to create, for example, a pattern on the surface.

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.
摘要:
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.
