Idexx开发出疯牛病抗原检测试剂盒

Idexx实验室开发了一种用于检测牛海绵状脑病（BSE）的酶免疫检测（EIA）试剂盒，这种疾病也被叫做疯牛病。

这种试剂盒被研制并得到了Freedom EVO液体操作平台、哥伦布Pro微型洗板机和Tecan US的Sunrise吸光检测仪的确证。BSE检测是一种抗原捕获EIA方法，用于检测朊病毒蛋白质(PrPsc)的异常构造，这种致病蛋白质与感染牛的mortem后脑组织的BSE发病率相关。快速mortem后样本的筛查方法，是确保BSE感染产品不进入市场销售的关键。

使用Tecan的Freedom EVO自动样本处理器，处理器具有8个吸头液体操作臂，这种检测方法是高通量全自动的方法，适合BSE根除项目、牛群控制以及屠宰场监测方案。

Idexx实验室市场部经理Neveda Djuranovic解释说：“自动化的Idexx检测操作相当简单。Tecan平台能够在5小时内处理9个板（828个样本），帮助BSE实验室提供了处理BSE样本的最佳选择。”
 
Antigen Test Kit for Mad Cow
 
A test kit with an enzyme immunoassay (EIA) for bovine spongiform encephalopathy (BSE), also known as mad cow disease, has been developed by Idexx Laboratories, Inc. (Westbrook, Maine).

The kit was developed and validated by the Freedom EVO liquid handling platform, the Columbus Pro micropolate washer, and the Sunrise absorbance reader of Tecan US (Research Triangle Park, NC, USA). The BSE test is an antigen-capture EIA for detection of the abnormal conformation of the prion protein (PrPsc), which has been associated with incidences of BSE in post-mortem brain tissues from affected cows. Methods for rapid screening of post-mortem samples are essential to ensure that BSE-tainted products do not enter the market.

Using Tecan’s Freedom EVO robotic sample processor with 8-tip liquid-handling arm, the assay can be fully automated for high throughput applications, making it suitable for use in BSE eradication programs, herd management, and abattoir surveillance programs.

“It is extremely easy to run the Idexx test with automation,” explained Nevena Djuranovic, marketing manager, Idexx. “The Tecan platform can run nine plates (828 samples) in five hours, giving BSE laboratories an excellent option for processing BSE samples.”
