  • Patent number: 9976940
    Abstract: The present invention relates to a composition for DNA staining, which can be safely used for researchers, can prevent DNA photocleavage, and can be applied to various fields. According to the present invention, when DNA is stained by using a fluorescent protein and a particular peptide bound to DNA, such a fluorescent protein-peptide is safe to researchers, suppresses DNA photocleavage, and allows reversible staining, thereby enabling efficient DNA staining. Therefore, the composition for DNA staining of the present invention can be variously used in DNA-related research.

  • Patent number: 8034550
    Abstract: Arrays of distinct chemically reactive materials used for assaying or screening are assembled by arranging premanufactured strips, each having a linear array of chemically reactive materials on its surface, into a frame to be exposed to a substance to be analyzed. The strips provide great flexibility in generating different types of arrays while still permitting efficiencies to be gained by batch processing of each strip type. The arrays further provide for novel read-out and reaction promotion techniques making use of the ability of the strips to direct and received energy to and from particular sites.

  • Patent number: 7831392
    Abstract: A method and system are provided for comparing ordered segments of a first DNA restriction map with ordered segments of a second DNA restriction map to determine a level of accuracy the first DNA map and/or the second DNA map. In particular, the first and second DNA maps can be received (the first DNA map corresponding to a sequence DNA map, and the second DNA map corresponding to a genomic consensus DNA map as provided in an optical DNA map). Then, the accuracy of the first DNA map and/or the second DNA map is validated based on information associated with the first and second DNA maps. In addition, a method and system are provided for aligning a plurality of DNA sequences with a ordered DNA restriction map. The DNA sequences and the DNA map are received (the DNA sequences being fragments of a genome and the DNA map corresponding to a genomic consensus DNA map which relates to an optical ordered DNA map).

  • Patent number: 7049074
    Abstract: A method for observing and determining the size of individual molecules and for determining the weight distribution of a sample containing molecules of varying size, which involves placing a deformable or nondeformable molecule in a medium, subjecting the molecule to an external force, thereby causing conformational and/or positional changes, and then measuring these changes. Preferred ways to measure conformational and positional changes include: (1) determining the rate at which a deformable molecule returns to a relaxed state after termination of the external force, (2) determining the rate at which a molecule becomes oriented in a new direction when the direction of the perturbing force is changed, (3) determining the rate at which a molecule rotates, (4) measuring the length of a molecule, particularly when it is at least partially stretched, or (5) measuring at least one diameter of a spherical or ellipsoidal molecule.

  • Patent number: 6874968
    Abstract: This invention relates to pockets for holding a single or a small batch of sheets of paper, and particularly to the construction of an enclosure which provides “direct write” storage and access for a top leaf enclosed therein, where one entry lip of the pocket is on a border of one edge of the pocket forming a “book edge” for retaining the margin side of a leaf, and dual corner tab pockets are on the opposing edge's corners for retaining one or both corners opposing the margin edge of said leaf, thereby allowing the secure entry of one or more leaves therein, allowing the encoding of the sequence position of the leaf when placed therein as to a place in either “last in first seen” or “last in last seen” position, offering secure sequential viewing along the book edge when the ends secured under the corner tabs are both free, and providing for direct writing on the surface of the top leaf when the pocket is laid face up.

  • Patent number: 6833172
    Abstract: What is provided is a leaf having adhesive on one side which is formed as a plurality of panels and has a series of fold hints between panels thereof, where the folds hints make folding of each panel onto the other easy, and where the fold hints are provided either by the unique shape of the panels one to the next, or by lines of perfection. The invention provides such a sticky leaf that can be lifted up and formed into a loop by folding on the perf hints and to the delivery of such a sticky leaf as a sheet of multiple leaf members, a roll, or a individual leafs.

  • Patent number: 6679418
    Abstract: This invention relates to multi-sectioned file folders, and particularly to the construction of an integrally formed self sectioning file folder having at least a sectioning panel formed between a front and a rear cover. The invention provides for the self-sectioning panel as part of a pocket panel which pocket panel may be formed as a pocket on the front or rear cover of the file folder by a series of folding and a sealing operation. The invention provides for the formation of such a self-sectioning panel of “book mark” strips for separating piles of paper, formed from a single panel sectioned and continuously folded piece of material, where the book-mark array can be formed by only two folds and a sealing operation.
