摘要:
It is to provide a method for determining allergic diseases with a high sensitivity and accuracy which enables multilateral and global analysis with a minute amount of sample, even using body fluid other than blood such as saliva, nasal discharge and tears as a sample, particularly by suppressing nonspecific reaction as much as possible. A chemically modified diamond/DLC (Diamond-like Carbon) chip is activated with a reacting reagent, a coupling reaction with a peptide comprising allergen or allergen epitope is conducted, and a sample such as saliva, tears, and nasal discharge which has undergone pressure filtration with a low protein-adsorbing filter, is contacted with an allergen determination chip to which washing and blocking operations have been performed on unreacted active groups, and an allergen recognizing antibody in the sample captured by the allergen determination chip is detected by immunoassay using a labeled secondary antibody, wherein a glycine-containing solution is used for a washing solution and/or blocking solution used in the washing and blocking operations, is used.

The present invention provides a novel method for detecting mammary cancer cells which uses, as an index, an expression level of a specific gene in human mammary cancer tissue (or cells). The method is characterized by including (1) measuring an expression level of a gene having a specific nucleotide sequence in human mammary cancer tissue (or cells), (2) measuring an expression level of the gene in human normal mammary gland tissue (or cells), and (3) detecting mammary cancer cells on the basis of the difference between measurement values obtained in (1) and (2).

[Object] To newly develop a method whereby walnut can be simply, rapidly and accurately separated and distinguished from pecan nut. [Means for Resolution] Due to the increase in the number of patients with the walnut allergen and the increase of import of pecan nut which is an edible nut belonging to the family Juglandaceae, recently in Japan, the development of a method for detecting walnut and the nut in a discriminative manner is urgently needed. With attention focused on the chloroplast matK gene with the apparent gene sequence, we developed a PCR method for specifically detecting nuts of the family Juglandaceae and identified the matK sequence of pecan nut to establish a method for discriminating walnut and pecan nut from each other using restriction enzymes, for discriminating walnut and pecan nut from each other.
摘要:
It is intended to provide a means of estimating the secondary processing properties of wheat flour obtained from harvested wheat in the early stage before the maturation of a wheat seed. Namely, a method of estimating the secondary processing properties of a fully matured wheat seed which comprises measuring the expression amount of at least one gene selected from among genes specified by any of the base sequences represented by SEQ ID NOS:1 to 121 in an immature wheat seed.

The present application provides a human gene over-expressing animal, which is a non-human animal carrying a human hematopoietic prostaglandin D 2 synthase gene in its somatic cell chromosome and expressing a large amount of human prostaglandin D 2 synthase, wherein the animal is one obtained through ontogenesis of a totipotency cell of a non-human animal or offspring of the obtained animal, and the totipotency cell is introduced with said synthase gene. The present application also provides a method of using the transgenic animal for testing in vivo activity of a candidate for anti-allergy medicines, sleep-controlling substances and candidates for anti-obesity.
