A signal-off-quantum-dot-based sensor for detecting the presence of a target molecule comprising: an aptamer probe having a nucleotide sequence which specifically interacts with the target molecule by sequence-dependent interaction, wherein the aptamer probe is sandwiched between (a) an oligonucleotide which is immobilized on the surface of a quantum dot (QD), and (b) a fluorophore-labeled oligonucleotide, wherein when the sensor is excited by an energy source: (i) in the absence of specific interaction between the target molecule and the aptamer probe, a baseline signal is emitted, and (ii) in the presence of specific interaction between the target molecule and the aptamer probe, a detection signal is emitted, wherein the baseline signal is greater than the detection signal, whereby the presence of the target molecule is detected.

The present invention provides methods and compositions for attenuating expression of a target gene in vivo. In general, the method includes administering RNAi constructs (such as small-interfering RNAs (i.e., siRNAs) that are targeted to particular mRNA sequences, or nucleic acid material that can produce siRNAs in a cell), in an amount sufficient to attenuate expression of a target gene by an RNA interference mechanism, e.g., in a sequence-dependent, PKR-independent manner. In particular, the subject method can be used to alter the growth, survival or differentiation of cells for therapeutic and cosmetic purposes.

Unitary hybridization probes having stem-and-loop structures, wherein the stem portion of the structure comprises a pair of interactive arms that are substantially prevented from interacting with target polynucleotides. One arm of the invented parallel-stem hybridization probe has a backbone polarity opposite that of the target-complementary loop sequence of the probe. Rather than interacting in an antiparallel fashion, the arms of parallel-stem hybridization probes interact in a parallel fashion. The arms of the invented dual inversion probes interact in a conventional antiparallel fashion, but have backbone polarities opposite that of the target-complementary loop portion of the probe. Arm portions of the inversion probes do not substantially contribute to sequence-dependent stabilization of probe:target hybrids. Incorporating inversion linkages into the structures of these probes dramatically simplifies the process of designing stem-and-loop hybridization probes.

A method, computer program product, and computer system for generating a timing sequence for activating resources linked through time dependency relationships. A Direct Acyclic Graph (DAG) includes nodes and directed edges. Each node represents a unique resource and is a predefined Recovery Time Objective (RTO) node or an undefined RTO node. Each directed edge directly connects two nodes and represents a time delay between the two nodes. The nodes are topologically sorted to order the nodes in a dependency sequence of ordered nodes. A corrected RTO is computed for each ordered node after which an estimated RTO is calculated as a calculated RTO for each remaining undefined RTO node. The ordered nodes in the dependency sequence are reordered according to an ascending order of the corrected RTO of the ordered nodes to form a timing sequence for activating the unique resources represented by the multiple nodes.

A wizard is utilized when creating a server-based transactional Web page application. The wizard keeps track of the interdependencies of the Web pages, any data accesses required for any of the Web pages, and any rules for presenting a different sequence of Web pages based upon differing aspects of anticipated user input. The wizard can then be used to access the required data if a user selection is made to download the application and run the application off-line at a client that is disconnected from the network. When running off-line, the wizard plays back the downloaded pages of the application in a sequence dependent upon the tracked interdependencies and received user input. When running off-line, the wizard controls the dynamic presentation of the downloaded pages and provides the required data to enable the transactional pages of the application to be completed. The wizard, in conjunction with a browser running at the client, automatically submits the completed Web pages of the application to the server when the client is reconnected to the network.

Herein is reported a method for reducing the aggregation of an immunoglobulin in solution comprising the steps of i) comparing the amino acid sequence of the fourth framework region of the heavy chain of an antibody with a reference or germline sequence and determining whether one or more threonine residues and/or serine residues have been replaced by a different amino acid residue, and ii) modifying the amino acid sequence of the immunoglobulin by reverting the exchanged threonine residues and/or serine residues back to threonine or serine of the reference or germline sequence and thereby reducing the aggregation of an immunoglobulin in solution.

The present invention is directed to a sequence dependent polynucleotide nanomechanical device based on a nucleic acid paranemic crossover (PX) molecule which is a four-stranded structure related to parallel double crossover molecules, except that every possible crossover takes place. Eliminating two crossovers leads to a topoisomer, termed JX₂, in which one pair of ends are switched (rotated 180°) while the other pair of ends remain the same. The device can be cycled between the two states, PX and JX₂, by replacing single strands that set the state to be PX or JX₂.

A method of obtaining fluorochromes that bind to specific sites on proteins is presented. The method consists of synthesizing a peptide bearing a sequence from a parent protein and a second peptide of similar composition but with a scrambled sequence. Each peptide is then added to a test fluorochrome at similar concentrations, and a difference in fluorescence is obtained. A difference in fluorescence indicates a sequence dependent interaction between the peptide and fluorochrome. A large number of fluorochromes can be screened using the two peptides to find one binding in a sequence dependent fashion. This fluorochrome can then be tested for binding to the original full-length protein. The fluorochrome can then serve as scaffold in medicinal chemistry. The fluorochrome/peptide interaction and resulting fluorescence can be inhibited by non-fluorescent test compounds, which are compounds that bind to this peptide. Thus. the peptide/fluorochrome interaction can provide assays screening for therapeutic drugs binding to this site on the protein.
