Abstract:
A holder for an array of bundles containing multiple fiber optic strands provides a pattern of openings into which one each of each bundle is fit. The openings may (but need not) penetrate the full holder thickness to permit working with bundles from either bundle end. In one embodiment the holder thickness equals the bundle length, and the holder is sized similarly to a microscope slide. An alternative embodiment temporarily retains bundles in a desired registration and subjects the retained bundles to molten material such as wax that is allowed to harden around the bundles and become the holder. A modular holder comprises laminates that each contain parallel grooves sized to receive a bundle. A holder for a single bundle includes cooperating grip-like members, one of which is pivotably attached and biased toward the other member. A common form factor may be used for each holder type to facilitate retaining holders in a common docking station.
Abstract:
Oligonucleotide analogue arrays attached to solid substrates and methods related to the use thereof are provided. The oligonucleotide analogues hybridize to nucleic acids with either higher or lower specificity than corresponding unmodified oligonucleotides. Target nucleic acids which comprise nucleotide analogues are bound to oligonucleotide and oligonucleotide analogue arrays.
Abstract:
Disclosed in certain aspects herein are methods and compositions for the assembly of genes and even larger nucleic acid molecules, and methods of using assembled nucleic acids, e.g., as synthetic biology tools and/or products.
Abstract:
The invention relates to sensor compositions comprising a composite array of individual arrays, to allow for simultaneous processing of a number of samples. The invention further provides methods of making and using the composite arrays. The invention further provides a hybridization chamber for use with a composite array.
Abstract:
Methods for discriminating between fully complementary hybrids and those that differ by one or more base pairs and libraries of unimolecular, double-stranded oligonucleotides on a solid support. In one embodiment, the present invention provides methods of using nuclease treatment to improve the quality of hybridization signals on high density oligonucleotide arrays. In another embodiment, the present invention provides methods of using ligation reactions to improve the quality of hybridization signals on high density oligonucleotide arrays. In yet another embodiment, the present invention provides libraries of unimolecular or intermolecular, double-stranded oligonucleotides on a solid support. These libraries are useful in pharmaceutical discovery for the screening of numerous biological samples for specific interactions between the double-stranded oligonucleotides, and peptides, proteins, drugs and RNA. In a related aspect, the present invention provides libraries of conformationally restricted probes on a solid support. The probes are restricted in their movement and flexibility using double-stranded oligonucleotides as scaffolding. The probes are also useful in various screening procedures associated with drug discovery and diagnosis. The present invention further provides methods for the preparation and screening of the above libraries.
Abstract:
The invention relates to DNA sequencing by synthesis techniques, including those utilizing the detection of pyrophosphate (PPi) generated during the DNA synthesis reaction (pyrosequencing). The methods and compositions utilize biosensor arrays comprising microspheres distributed on a surface.
