VIDAS全自动酶标免疫测试系统.

VIDAS是生物梅里埃公司生产的一种全自动免疫荧光酶标仪，在微生物检测中主要是利用酶联免疫的原理对微生物或毒素等进行筛选检测。

mini-VIDAS是一台全自动荧光免疫分析仪，它集合计算机、键盘及打印机于一身。此免疫仪的反应市控制整个酶联反应的操作直至打印结果。内置计算机管理数据及报告。Mini-VIDAS由两个独立的仓各含6个试验通道，可同时进行不同的VIDAS试验。

功能强

仪器本身灵活性高，可同时进行VIDAS的不同试验(80个标本/每工作日)，也可单个测试运作。经48小时增菌过程后，多数试验可于50分钟内结束。快速筛选样本。既可对食品中的毒素进行检测,也可对主要病原菌进行检测。

简单/快速

全过程自动完成，将即可用试剂插入仪器中，然后由机器分担所有工作，直至打印报告。即可用试剂节省操作时间，也可配套本公司的成品增菌培养基一并使用。

可靠结果

客观量度及分析减低人手误差。整个过程标准化、自动化。内设自检系统，无交叉污染。

独特创新

１．全自动系统　２．参数不断更新　３．工业微检室的高科技代表

国际认可的标准

获得的国际认可保证了提供的微生物学检测的结果是公认的

原理

应用酶联免疫法，最后测蓝色荧光（ELFA）抗原（细菌、蛋白）的检测是应用一种夹心的技术，包被针上有抗体包被，所测得的荧光与标本中抗原的含量成正比。

测试范围

用以食品及环境样本中的致病菌包括：沙门氏菌、李斯特菌、单核细胞增生李斯特菌、葡萄球菌肠毒素、大肠埃希菌O157、弯曲菌、免疫浓缩沙门氏菌、免疫浓缩大肠埃希菌O157。

即可用试剂

VIDAS一次性即可用试剂分为
2部分：
　　 SPR，固相接受器，其内侧由抗体包被，此包被针作为固相吸管功能
　　 条形码标记试剂条，含所有所需试剂，取出即可用。试条类别由试条上颜色标贴及3字母的标志识别。

VIDAS and mini VIDAS : automated immunoanalysers

VIDAS is a multi-parameter automated immunoanalyser. It comprises an analytical module, a computer and a printer. The analytical module automatically performs all stages of the analysis, including printing out the full results. It contains five sections, each accepting 6 tests, and can handle 60 tests per hour. Thanks to its speed of reaction and sectioned architecture, VIDAS? is the ideal system for handling series of analyses and urgent tests. The computer module is used to manage and print out the results. It can handle up to four analytical modules simultaneously, giving the system a capacity of 240 tests per hour.

mini VIDAS is a compact version of the VIDAS system, with a built-in computer, keyboard and printer. It has 2 independent sections each accepting 6 tests, and can process up to 12 samples simultaneously.

The VIDAS technology is reliable in all situations, as confirmed by our operation mini VIDAS? on Mont Blanc.

With a range up to 70 assays VIDAS tests have applications in clinical diagnostics and industrial microbiological testing.

VIDAS test

VIDAS tests use ELFA technology (Enzyme Linked Fluorescent Assay), associating enzyme marking and fluorescence measurement. It is used on the VIDAS and mini VIDAS automated analyzers. Based on an inter-sample anti-contamination principle, VIDAS? tests are presented in individual, ready-to-use form. They contain a SPR and a strip :

the SPR (Solid Phase Receptacle) is the solid phase of the reaction. It is a disposable item, and acts as a sampling needle. This concept eliminates potential inter-sample contamination.

the strip contains all the reagents, ready for use.

At each stage in the immunoanalysis, the SPR repeatedly takes up the reagent and transfers it into the various wells of the strip, through to the final stage of the analysis. The last well is the reading well, where the final intensity of the reaction is measured by fluorescence.

VIDAS menu for industrial testing

VIDAS offers 8 assays for the rapid detection of pathogens in food products and environmental samples :

VIDAS Listeria, for detection of Listeria (validated by the AFNOR *)

VIDAS Listeria monocytogenes, for specific detection of Listeria monocytogenes (validated by the AFNOR *)

VIDAS Salmonella, for detection of Salmonella (validated by the AFNOR *)

VIDAS ICS, for salmonella immunoconcentration

VIDAS Staph enterotoxin, for detection of Staphylococcus A, B, C1, C2, C3, D and E enterotoxins

VIDAS Campylobacter, for detection of Campylobacter

VIDAS ECO, immunodetection of the potential presence of E.coli O157 using an optimized protocol in less than 24 hours.

VIDAS ICE, immunocapture to simplify the confirmation stage of the presence of E.coli O157 which is particulary delicate using the conventional method and to considerably reduce waiting time by avoiding time-consuming culture stage
