  • Patent number: 7488595
    Abstract: The present invention generally relates to methods and apparatuses for amplifying nucleic acid sequences using immobilized DNA polymerase. More particularly, it relates to methods and apparatuses useful for amplifying target nucleic acid sequences by forming a plurality of reaction regions in which polymerase chain reaction (PCR) can occur, positioning immobilized DNA polymerase in a specific reaction region, and circulating DNA through the reaction regions. The present invention provides those methods and apparatuses that allow simple separation and recovery of the DNA polymerase after the amplification, that can be operated not only with thermostable DNA polymerases but also with non-thermostable DNA polymerases, and that are simpler in their designs and processes so that they can be readily integrated into complex devices such as Lab-on-a-chip.

  • Patent number: 7238505
    Abstract: The present invention relates to a DNA polymerase immobilized by covalent bonding. More particularly, the present invention relates to an immobilized DNA polymerase whose activity is maximally preserved by masking the active site of the DNA polymerase and optimizing interaction of the masked molecule to the substrate material. In one embodiment, the average activity of the immobilized DNA polymerase is more than about 10% relative to that of the solution phase DNA polymerase. Further provided by the invention are methods and kits for performing polymerase chain reactions (PCR).

  • Publication number: 20040152122
    Abstract: The present invention provides a nucleic acid sequence amplification method and apparatuses thereof that are simple in the design and easy to miniaturize and integrate into complex apparatuses, with capability of using DNA polymerases that are not thermostable. In the present invention, a plurality of heat sources are combined to supply or remove heat from specific regions of the sample such that a specific spatial temperature distribution is maintained inside the sample by locating a relatively high temperature region lower in height than a relatively low temperature region.

  • Publication number: 20040091602
    Abstract: The present invention relates to a method for immobilizing a biologically active molecule on a supporting material. In one embodiment, the invention relates to an efficient immobilization method that maximally preserves the biological activity of the immobilized molecule by masking the active site of the molecule and optimizing interaction of the masked molecule to the supporting material.

  • Patent number: 6198212
    Abstract: A display system includes a cathode ray tube having a panel and a funnel which is coupled to the panel forming a seal and has an external graphite layer formed on the outer circumferential surface thereof; a case in which a space is formed to provide room for the cathode ray tube to be installed therein; and material for anion generation disposed at a predetermined position with respect to the cathode ray tube or the case. The anions generated from the material for anion generation is beneficial to a user of a display system. Also, a transferring portion is provided to control the transfer distance of anions to the user.
