  • Polyamide acid and polyimide, and optical material
    Patent number: 6924348
    Abstract: A polyimide excelling in heat resistance, chemical resistance, water repellency, dielectric characteristics, electrical characteristics, and optical characteristics and a polyamide acid useful as the raw material therefor are provided. Specifically, a polyamide acid containing a chlorine atom and a fluorine atom and comprising a repeating unit represented by the following formula (1): (wherein X and X? independently denote a divalent organic group; Y and Y? independently denote a chlorine, bromine, or iodine atom; p and p? denote independently denote the number of fluorine atom {F in the formula (1)} bonded to the relevant benzene ring, representing an integer of 0-3; q and q? independently denote an integer of 0-3; and p+q total 3, and p?+q? total 3).

  • DNA test for SCA-10
    Patent number: 6855497
    Abstract: Included is a method for detecting spinocerebellar ataxia type 10 (SCA10) by measuring the presence or absence of a DNA expansion in a gene locus associated with spinocerebellar ataxia type 10. The method employs extracting DNA from a sample to be tested, amplifying the extracted DNA; and identifying the presence or absence of a DNA expansion in the amplified extension products. Also included in the present invention are a kit for diagnosis of SCA10 and non-human transgenic eukaryotes that are not expressing or overexpressing SCA10.
