What is it indicated for?
In order to confirm HSV-1-infections physictans frequently use tissue-culture techniques. This involves obtaining patient samples, inoculation of these samples into established cell lines (Such as MRC-5 cells) and monitoring these cells for HSV-1 induced cytopathology. Frequently the cells inoculated with patient sample are then stained as an aid in the diagnosis of HSV-1 infections. HSV-1 Antigen Control Slides are quality control materials used to…

In order to confirm HSV-1-infections physictans frequently use tissue-culture techniques. This involves obtaining patient samples, inoculation of these samples into established cell lines (Such as MRC-5 cells) and monitoring these cells for HSV-1 induced cytopathology. Frequently the cells inoculated with patient sample are then stained as an aid in the diagnosis of HSV-1 infections.
HSV-1 Antigen Control Slides are quality control materials used to confirm the accuracy of staining reagents used in cell culture confirmatory assays for the detection of HSV-1. Each individual slide contains two wells of fixed cells, one HSV-1 infected well and one uninfected well. The two wells of cells on the HSV-1 Antigen Control Slide are stained concomitantly with the cells inoculated with patient sample providing both a positive and negative control for the staining reagents and procedure. Lack of staining of the positive well indicates a failure of one or more components of the staining reagent.
