  • Patent number: 6927065
    Abstract: A method for determining the length and velocity of single elongated macromolecules is disclosed. In particular, the present invention relates to methods and apparatus for determining the velocity of elongated polymeric molecules moving relative to one or more detection stations, as well as to methods and apparatus for determining the length of such molecules and the distance between landmarks that may be present on such molecules. The invention makes use of time correlated measurements of signal amplitude profiles that result from interactions between each detection station and portions of each macromolecule.

  • Publication number: 20040235014
    Abstract: The invention provides methods and systems for improved spatial resolution of signal detection, particularly as applied to the analysis of polymers such as biological polymers. Some of the methods and systems comprise differentially tagging polymers in order to increase resolution. Some of the methods and systems comprise techniques for improving the precision of separation distance measurements, without necessarily requiring improvements in the known detection resolution of prior art systems.

  • Patent number: 6790671
    Abstract: The invention relates to new systems, methods and products for analyzing polymers and in particular new systems, methods and products useful for obtaining sequence information from polymers. The invention has numerous advantages over prior art systems and methods used to obtain sequence-related information. Using the methods of the invention the entire human genome could be analyzed several orders of magnitude faster than could be accomplished using conventional technology. In addition to obtaining sequencing information for the entire genome, the systems, methods and products of the invention can be used to create comprehensive and multiple expression maps for developmental and disease processes. The ability to analyze an individual's genome and to generate multiple expression maps will greatly enhance the ability to determine the genetic basis of any phenotypic trait or disease process.

  • Publication number: 20040166025
    Abstract: The present invention provides structures and methods that allow polymers of any length, including nucleic acids containing entire genomes, to be stretched into a long, linear conformation for further analysis. The present invention also provides structures and methods for selecting and stretching polymers based on their lengths. Polymers are loaded into a device and run through the structures. Stretching is achieved by, e.g., applying shear forces as the polymer passes through the structures, placing obstacles in the path of the polymer, or a combination thereof. Since multiple molecules may be stretched in succession, extremely high throughput screening, e.g., screening of more than one molecule per second, is achieved.

  • Patent number: 6772070
    Abstract: The present invention relates to methods and apparatuses for analyzing molecules, particularly polymers, and molecular complexes with extended or rod-like conformations. In particular, the methods and apparatuses are used to identify repetitive information in molecules or molecular ensembles, which is interpreted using an autocorrelation function in order to determine structural information about the molecules. The methods and apparatuses of the invention are used for, inter alia, determining the sequence of a nucleic acid, determining the degree of identity of two polymers, determining the spatial separation of specific sites within a polymer, determining the length of a polymer, and determining the velocity with which a molecule penetrates a biological membrane.

  • Patent number: 6762059
    Abstract: The present invention relates to methods and apparatuses for characterization of single polymers. In particular, the invention relates to methods and apparatuses for determination of the velocities of single elongated polymers. Center-of-mass velocity, center-to-center velocity, end-to-end velocity and rise-time velocity are determined using time-correlated measurements of single elongated polymers in two or more detection zones. The invention also relates to methods of determinating lengths and molecular masses of single polymers and to methods of determining the distance between landmarks on a single polymers based on their velocities. The invention further relates to methods of single-molecule DNA restriction fragment analysis.

  • Publication number: 20020110818
    Abstract: The invention relates to methods and products for analyzing polymers. The polymers are analyzed by reconstructing sequence information from population data sets. The data sets include information about polymer dependent impulses arising from the polymers. The invention is also a method for linearly analyzing polymers by assessing the intensity of a signal arising from the polymer. The signal is generated as units and/or units specific markers pass a fixed station. The quantitative intensity of the signal is proportional to the number of units and/or unit specific markers giving rise to the signal.
