    • A diagnostic assay for detecting the presence of an infectious herpesvirus in a specimen and a genetically engineered cell line for use in such assay are disclosed. The cell line used in the assay expresses a reporter gene only if infectious herpesvirus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpesvirus, allowing a sufficient period of time for the herpesvirus infectious cycle to proceed, and detecting and quantifying the number of herpesvirus-infected cells to determine the number of infectious herpesvirus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpesvirus which is stably transformed with a chimeric gene comprising a herpesvirus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpesvirus. A kit for such assay is also provided.
    • 公开了用于检测样本中的感染性疱疹病毒的存在的诊断测定法和用于这种测定的基因工程细胞系。 只有感染性疱疹病毒存在于样本中时,测定中使用的细胞系才能表达报告基因。 该测定包括用疑似含有疱疹病毒的标本接种DNA转染的细胞系,允许疱疹病毒感染循环的足够的时间进行,并检测和定量疱疹病毒感染细胞的数量以确定感染的数量 样本中的疱疹病毒病毒粒子。 细胞系是由疱疹病毒感染易感染的DNA转染的细胞系,其用包含疱疹病毒诱导型启动子和编码酶的基因的嵌合基因稳定转化,所述酶的表达依赖于和与其成比例 存在疱疹病毒。 还提供了用于这种测定的试剂盒。
