  • Patent number: 11932859
    Abstract: Methods are provided herein for assembling at least two nucleic acids using a sequence specific nuclease agent (e.g., a gRNA-Cas complex) to create end sequences having complementarity and subsequently assembling the overlapping complementary sequences. The nuclease agent (e.g., a gRNA-Cas complex) can create double strand breaks in dsDNA in order to create overlapping end sequences or can create nicks on each strand to produce complementary overhanging end sequences. Assembly using the method described herein can assemble any nucleic acids having overlapping sequences or can use a joiner oligo to assemble sequences without complementary ends.

  • Patent number: 9335533
    Abstract: A new apparatus and method of delivering light to the hack aperture of a High Numerical Aperture (NA) Microscopy Objective lens for Total Internal Reflectance Microscopy (TIRFM) is provided. The apparatus and method include pumping light generated by a laser through an optical fiber which is optically coupled to the objective lens by a collimating optical element, such as, for example a lens or prism. The apparatus and method also include providing a fiber axial translator which is mechanically adjustable for focusing the laser light optically coupled to the objective lens. The apparatus also includes a mechanical coupler for mechanically coupling the apparatus to the object lens such that the laser light optically coupled to the objective lens can be adjusted to exceed, or not exceed, a critical angle associated with TIRFM illumination.

  • Patent number: 7885498
    Abstract: A sample slide, launch system, and method for microscopy having two optical fibers positioned proximate a sample slide with optical fiber mounting elements to deliver EMR to a surface of the sample slide at a critical angle for total internal reflection microscopy. In one exemplary embodiment, the EMR from the first optical fiber and the EMR from the second optical fiber may have different polarization states and/or wavelengths.

  • Patent number: 7711225
    Abstract: A sample slide, launch system, and method for microscopy having a fiber insertion portal terminating within the sample slide and having a fiber insertion axis such that when an optical fiber is inserted within the fiber insertion portal the optical fiber is positioned so to deliver an EMR to a surface of the sample slide at a desired angle.

  • Patent number: 7075046
    Abstract: A system and method for referencing an objective lens to a desired plane of focus. In one embodiment, a dichroic element is utilized to reflect energy of one or more wavelengths that has passed through an objective lens to a detector for determining a position of the objective lens to a desired plane of focus. The objective lens may be manually and/or automatically focused to the desired plane of focus.
