This Anti-Cytomegalovirus Antibody, immediate early, clone 7D12.2 is validated for use in IF, WB, IC, IH for the detection of Cytomegalovirus.

Reacts with an immediate early protein M.W. 68 kD. Can detect CMV infection 1 hour post-infection exhibiting a nuclear and cytoplasmic staining which reaches peak intensity between 8-24 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
