Specificity
Reacts with Immediate Early 2 protein (IE2) and its fragments. Recognizes a can epitope near the carboxy-end that includes an epitope found in IE2 86, IE2 60 and IE2 40. In western blot recognizes proteins at apparent molecular weights of 86, 68-72, 55 and 38 kD. Can detect CMV infection 1 hour post-infection exhibiting nuclear and/or intranuclear inclusion staining with reaches peak intensity at 3 hours.
With CMV the antigens expressed at different times are listed as:
Immediate Early (alpha gene expression): those antigens expressed at 3-12 hrs post-infection generally involved in Transcription such as 72kD major phosphoprotein and a few other other antigens at 60 - 80kD.
Early Antigen (beta genes) a.k.a. Delayed Early or Intermediate Early: expressed at 12-24hrs post-infection. Generally enzymes and one virion structural gene preceding viral DNA synthesis.
Late Antigen (gamma genes): expressed at 36-48hrs post-infection. Generally structural proteins. Major protein = 55kD
