Technical Data
Cytomegalovirus, 65kD Late Antigen (CMV pp65, 65kD Matrix Phosphoprotein, 65kD Phosphoprotein, HCMV, Human Herpes virus 5, HHV-5, HHV5, HHV5wtgp077, PP65, Tegument Protein pp65, Tegument Protein UL83, UL83)
Cytomegalovirus (CMV) is an opportunistic pathogen that infects lung, kidney, gut and other organs in immunologically immature individuals or in immunosuppressed patients. An active CMV infection time course in immunosuppressed individuals is characterized by a period of several weeks of pp65 antigenemia that corre- lates with viral replication, before the onset of clinical symptoms. This pool of 2 antibodies will detect the pp65 antigen in tissues and cytospins.

Suitable for use in Immunofluorescence, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunofluorescence: 1:10-1:20
Western Blot: 1:1000
Immunohistochemistry: 1:200 for 1 hr. at RT
Optimal dilutions to be determined by the researcher.

Positive Control:
Western Blot: CMV-infected cells.
Immunohistochemistry: Cytomegalovirus-infected lung (nuclear and cytoplasmic staining pattern)
