Effective isolation of nucleic acids from samples containing viral materials is an essential step for accurate diagnosis of viral infections. The necessity of this critical step before analytical identification and diagnosis of viral infections is paramount to screening programs and to identifying and monitoring epidemics and pandemics. With molecular assays rapidly evolving into routine practice, clinical laboratories face several challenges, including presence of small amounts of viral nucleic acids in abundant levels of genomic DNA and total RNA, processing of various sample types, and carry-over of polymerase chain reaction inhibitors, which could significantly affect polymerase chain reaction and microarray results. MagaZorb nucleic acid isolation technology overcomes these challenges and offers a simple and reliable method for isolation of high-quality and high-yield nucleic acids. Although the MagaZorb technology is readily adaptable to automated platforms, it is also well suited to laboratories in remote areas of resource-poor countries, because a simple magnet is the only device required to perform the procedure manually. Performance characteristics and clinical application of the MagaZorb technology are briefly described here.
从含有病毒材料的样本中有效分离核酸是准确诊断病毒感染的关键步骤。在对病毒感染进行分析鉴定和诊断之前,这一关键步骤是至关重要的,这对于筛选程序以及识别和监测传染病和大流行具有重要意义。随着分子检测技术迅速成为常规实践,临床实验室面临着多种挑战,包括在大量基因组 DNA 和总 RNA 中存在少量病毒核酸、处理各种类型的样本以及聚合酶链反应抑制剂的残留,这些都会对聚合酶链反应和微阵列结果产生重大影响。MagaZorb 核酸分离技术克服了这些挑战,提供了一种简单可靠的方法来分离高质量和高产量的核酸。尽管 MagaZorb 技术很容易适应自动化平台,但它也非常适合资源匮乏国家偏远地区的实验室,因为手动操作仅需一个简单的磁铁。本文简要描述了 MagaZorb 技术的性能特点和临床应用。
