The object is to provide a lysis method and lysis treatment solution for efficiently lysing cells of variousbacteria in milk of a livestock animal to release a specific antigen substance contained in the cells for detecting whether causative bacterium of mastitis is abacterium or not by using the milk, as well as a detection method using an immunochromatographic device. There is provided a method for lysing abacterium, which comprises the step of mixing a lysis agent containing a lytic enzyme with milk obtained form a livestock animal to lyse abacterium existing in the milk. The lytic enzyme is preferably at least one selected from the group consisting of lysozyme, labiase, and &#x3b2;-N-acetylglucosaminidase.

[object Object]

Provided is a prepreg suffering little resin particle fall-off and little resin peeling during prepreg production and during handling in order to have excellent dielectric properties for PPE and favorable adhesiveness. A PPE-containing prepreg constituted of a base material and a curable resin composition including PPE particles, wherein the prepreg is characterized in that (1) PPE extracted from the prepreg using a mixed solvent of toluene and methanol in a mass ratio of 95:5 includes PPE particles (A) insoluble in the mixed solvent, (2) the amount of PPE contained in the PPE particles (A) is 70 mass % or higher, and (3) the number-average molecular weight of the PPE contained in the PPE particles (A) is 8,000-40,000.

Prepreg comprising polyphenylene ether particles

Provided is a curable resin composition which can provide a cured article having a low dielectric constant and a low dielectric tangent, and can also provide a cured article having excellent moldability at ordinary press-molding temperatures, excellent heat resistance and excellent adhesion properties. The present invention provides a curable resin composition containing a polyphenylene ether, wherein the average number of phenolic hydroxy groups is 0.3 or more per molecule of the polyphenylene ether, the resin flow amount of the curable resin composition upon curing is 0.3 to 15% inclusive, and a cured article having a dielectric tangent of 0.005 or less at 1 GHz and a glass transition temperature of 170&#xb0; C. or higher can be produced.
