Anti-Cytomegalovirus Antibody, late Antigen, clone 2D4.2

Reacts with a late protein M.W. 47-55 kD. Can detect CMV infection 24 hours post-infection exhibiting a cytoplasmic staining which reduces peak intensity at >72 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

Epitope: late antigen

Sucrose gradient purified CMV AD169 (ATCC).

Anti-Cytomegalovirus Antibody, late antigen, clone 2D4.2 detects level of Cytomegalovirus & has been published & validated for use in IF, WB, IH(P).

IFA at 1:400-1:800 on acetone fixed cells.

Works on paraffin embedded tissue sections.

Dilute with buffer pH 7.4-7.6 to desired working volume.

For extensive dilution, protein containing or other stabilizing medium should be used.

Final working dilutions must be determined by end user.
