Abstract: Described are systems and assays that monitor presence and/or quantity of herpesviruses viral proteins. Embodiments offer accurate detection and quantification of viral proteins from all temporal classes of viral replication. Three exemplary assays provide specific detection of: herpes simplex vims type 1 (HSV1), human cytomegalovirus (HCMV), and Kaposi's sarcoma-associated herpesvirus (KSHV). These assays can be utilized in combination with drug treatments, genetic modifications, or other perturbations to assess the impact of the intervention on viral protein production.
