  • Patent number: 10746742
    Abstract: Disclosed herein are methods of high-throughput mapping of viral neutralizing antibody epitopes. Also disclosed are in vitro immunoprecipitation-based adenoassociated virus Barcode-Seq-based methods of mapping viral neutralizing antibody epitopes. In some embodiments, a method of high-throughput mapping of viral NtAb conformational epitopes can be utilized, which may comprise HP scanning of mutant viral libraries, immunoprecipitation (IP), and/or next-generation sequencing (NGS) technology. In some embodiments, a method of identifying one or more dominant epitopes in a viral vector may comprise contacting a mutant capsid of a virus with serum from a subject previously exposed to the virus and immunopredpitating serum immunoglobulins from the serum. In various embodiments, the viral vector may be an AAV vector.

  • Patent number: 9648291
    Abstract: Provided is a light source device where the number of optical components is reduced without lowering an efficiency for light utilization. The light source device includes an excitation light source which generates blue laser light as excitation light, a phosphor wheel including a phosphor which is excited by the excitation light from the excitation light source to generate yellow fluorescent light, and a mirror which guides the excitation light from the excitation light source to the phosphor wheel and transmits the fluorescent light from the phosphor wheel, wherein the mirror includes a first region which reflects the excitation light and transmits the fluorescent light and a second region which transmits the fluorescent light and diffused excitation light which is diffused and reflected in the phosphor. The yellow fluorescent light and the diffused excitation light passing through the mirror are mixed to generate white light.

  • Patent number: 9618175
    Abstract: A vehicle lamp includes a phosphor which receives laser light (excitation light) emitted from a semiconductor light-emitting element to emit visible light, a reflector which reflects the visible light (illumination light) emitted from the phosphor forward, and an absorbing member which absorbs excitation light regularly reflected by a surface of the phosphor. A metal plate on which the phosphor is disposed to be inclined to cause the excitation light regularly reflected by the surface of the phosphor to be incident on the absorbing member. An upper end portion of the reflector is disposed at a position lower than a vertical position of the phosphor to prevent the regularly reflected excitation light from being incident on the upper end portion.

  • Publication number: 20160084461
    Abstract: Provided is a vehicle lamp for emitting illumination light having reduced color nonuniformity and luminance variation with a simple structure. The vehicle lamp comprises: a light source for emitting excitation light; a fluorescent body for emitting fluorescent light excited by the excitation light emitted from the light source; a diffuser for diffusing the excitation light specularly reflected on the surface of the fluorescent body; and a reflector for reflecting the fluorescent light emitted from the fluorescent body and the excitation light diffused by the diffuser ahead of a vehicle. The fluorescent body is arranged above the light source, and the reflection surface of the reflector is arranged to face the fluorescent body from the direction in which the light is specularly reflected on the fluorescent body toward the lower side of the fluorescent body.
