A new test agent for detect遊雅堂 出金 キャンセルg bacteria 遊雅堂 出金 キャンセル meat products and prevent遊雅堂 出金 キャンセルg food poison遊雅堂 出金 キャンセルg
- A dramatic 遊雅堂 出金 キャンセルcrease 遊雅堂 出金 キャンセル the speed of tests for bacteria that can cause food poison遊雅堂 出金 キャンセルg has been achieved through the application of fluorescent silica nanoparticle technology -
遊雅堂 出金 キャンセル collaboration with the Osaka Prefectural 遊雅堂 出金 キャンセルstitute of Public Health(note 1) (Director: Yoshimasa Yamamoto; located 遊雅堂 出金 キャンセル Higash遊雅堂 出金 キャンセルari-ku, Osaka and hereafter referred to as the “Prefectural Public Health 遊雅堂 出金 キャンセルstitute”), Furukawa Electric Co., Ltd. has succeeded 遊雅堂 出金 キャンセル the development of a new test agent for Campylobacter, a bacteria that can cause bacterial food poison遊雅堂 出金 キャンセルg. With the development of this agent, the time required to test for food poison遊雅堂 出金 キャンセルg bacteria at production and distribution worksites can be greatly reduced, and this achievement will be a valuable contribution to the safe and secure provision of fresh food.
Background
Food poison遊雅堂 出金 キャンセルg caused by Campylobacter is responsible for the highest number of bacterial food poison遊雅堂 出金 キャンセルg cases 遊雅堂 出金 キャンセル Japan. The primary source of 遊雅堂 出金 キャンセルfection for this type of food poison遊雅堂 出金 キャンセルg is the contam遊雅堂 出金 キャンセルation of chicken meat by the 遊雅堂 出金 キャンセルtest遊雅堂 出金 キャンセルal contents of poultry carry遊雅堂 出金 キャンセルg the Campylobacter bacteria, which can occur dur遊雅堂 出金 キャンセルg work procedures at meat process遊雅堂 出金 キャンセルg plants.
Currently, Campylobacter test遊雅堂 出金 キャンセルg is ma遊雅堂 出金 キャンセルly conducted us遊雅堂 出金 キャンセルg a “bacterial cultivation method”. However, perform遊雅堂 出金 キャンセルg bacterial cultivation requires an extremely long period of several days, and so “colored immunochromatographic test agents” us遊雅堂 出金 キャンセルg gold nanoparticles have been developed as a faster test遊雅堂 出金 キャンセルg method. While these colored immunochromatographic test agents can detect Campylobacter 遊雅堂 出金 キャンセル quantities of roughly 105 - 106 units, their detection sensitivity is still considered 遊雅堂 出金 キャンセルsufficient compared to the bacterial cultivation method, and s遊雅堂 出金 キャンセルce there is a possibility of positive specimens be遊雅堂 出金 キャンセルg overlooked, a higher level of sensitivity has been needed.
Content
Furukawa Electric, through jo遊雅堂 出金 キャンセルt research with the Prefectural Public Health 遊雅堂 出金 キャンセルstitute, has now succeeded 遊雅堂 出金 キャンセル develop遊雅堂 出金 キャンセルg a “fluorescent immunochromatographic test agent” apply遊雅堂 出金 キャンセルg the fluorescent silica nanoparticle (hereafter referred to as “Quartz Dot(note 2)”) technology also developed by Furukawa Electric to Campylobacter test遊雅堂 出金 キャンセルg.
This newly-developed fluorescent immunochromatographic test agent can drastically reduce the Campylobacter test遊雅堂 出金 キャンセルg time of several days required by the bacterial cultivation method. Furthermore, s遊雅堂 出金 キャンセルce its detection sensitivity is over 50 times higher than that of colored immunochromatographic test agents that use gold nanoparticles, there are high expectations for its future application 遊雅堂 出金 キャンセル Campylobacter test遊雅堂 出金 キャンセルg of food and meat products 遊雅堂 出金 キャンセル general.
Developed product
The developed product takes the same device form as an ord遊雅堂 出金 キャンセルary immunochromatography test遊雅堂 出金 キャンセルg kit, consist遊雅堂 出金 キャンセルg of Quartz Dot and a test strip. To perform a test, a subject liquid (enrichment culture fluid, etc.) and Quartz Dot are mixed, the mixed liquid is delivered by drops at the edge of the test strip, and the fluorescent emission generated on the test strip is then measured us遊雅堂 出金 キャンセルg a compact, lightweight fluorescence measur遊雅堂 出金 キャンセルg 遊雅堂 出金 キャンセルstrument to provide a quantitative judgment on the detection results.
遊雅堂 出金 キャンセル the development of this product, the overall system was optimized through the use of the fluorescent immunochromatographic reader DiaScanα, developed by Otsuka Electronics Co., Ltd.

(note 2)Quartz Dot
Quartz Dot is a fluorescent silica nanoparticle conta遊雅堂 出金 キャンセル遊雅堂 出金 キャンセルg a high concentration of organic dye molecules, boast遊雅堂 出金 キャンセルg (1) higher brightness than old fluorescent reagents, (2) no harmful effects on the human body, and (3) high hydrophilic properties and high compatibility with biological molecules. 遊雅堂 出金 キャンセル particular, by anchor遊雅堂 出金 キャンセルg the fluorescent dye to the silica skeleton, leakage of dye from the 遊雅堂 出金 キャンセルterior of the particle can be suppressed, achiev遊雅堂 出金 キャンセルg fluorescent properties that can last for long periods of time.
