Summary

最近开发的新颖的颗粒凝集法(PA)的测定利用病毒的受体分子,允许快速和容易识别的脊髓灰质炎病毒(PV)。在这篇文章中,我们将显示为光伏识别PA检测的过程。

Abstract

在全球根除脊髓灰质炎行动,从急性弛缓性麻痹(AFP)病例粪便标本中分离鉴定光伏实验室诊断起着至关重要的作用。在世界卫生组织(WHO)的全球脊髓灰质炎实验室网络,光电隔离和鉴定,目前正在通过细胞培养系统和实时RT – PCR检测,分别进行。在光伏根除后时期,简单和快速识别程序,将有利于快速确认在国家实验室的脊髓灰质炎病例。在本研究中,我们将展示的新型PA检测程序开发光伏鉴定。该PA检测采用光伏受体(PVR)的分子和病​​毒,是具体的和统一的光伏所有血清型的亲和力的互动。程序很简单(一个反应板的步骤程序)和反应2小时内可以得到快速的(结果),结果是直观地观察(观察明胶颗粒凝集)。

Protocol

1。维持液(MM)的制备和生长介质(GM) 对于MM和通用汽车公司的准备,请看到世界卫生组织 1脊髓灰质炎实验室手册。贝科改良Eagle培养基(DMEM),辅以2%胎牛血清(FCS)和10%FCS可以用作替代品的MM和通用分别。 2。反PV抗体的制备重组反光伏的抗体(RIVM光伏输入抗血清),加入水(0.5%毫升小瓶),每小瓶抗PV抗体(1型,2或3)。将此?…

Discussion

这个PA检测的独特之处是利用反光伏抗体,而不是2光伏检测PVR的分子。这允许特定的相互作用的一个统一的亲和力,所有三个血清型光伏3-6致敏的明胶颗粒与光伏。我们用于致敏的明胶颗粒immunoadhesin形式的PVR(PVR – IgG2a),因为单体形式的PVR只有适度的亲和力,以单一的结合位点上的病毒粒子(解常数10 -7〜-8号) 7, 8,成功地观察到具体的光伏株致?…
