A diagnostic assay for detecting the presence of an infectious herpes virus 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 herpes virus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpes virus, allowing a sufficient period of time for the herpes virus infectious cycle to proceed, and detecting and quantifying the number of herpes virus-infected cells to determine the number of infectious herpes virus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpes virus which is stably transformed with a chimeric gene comprising a herpes virus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpes virus. A kit for such assay is also provided.
An in vitro diagnostic method to detect infectious herpes virus in a specimen, said method comprising the steps of:
A genetically engineered cell line stably transformed with a sequence of DNA from a herpes virus family member wherein said herpes virus family member is Herpes Simplex Virus Types 1 and 2 and said sequence of DNA is comprised of a promoter from a UL39 gene wherein said promoter has properties of inducibility by transactivators of Herpes Simplex Virus Types 1 and 2, specificity for transactivators of Herpes Simplex Virus Types 1 and 2, and non-constitutive expression, operably linked to a reporter gene, the expression of the reporter gene being dependent upon and quantitatively proportional to the presence of the herpes virus.
A cell line identified as BHKICP6LacZ cells.
A cell line identified as BHKICP6LucA cells.
A kit for assaying for the presence of infectious herpes virus in a specimen, said kit comprising:
