Cytomegalovirus (CMV) Antigen

Viral antigen preparations from Antibodies.com support diagnostic assay development and infectious disease research targeting human cytomegalovirus. The 1mg liquid formulation is supplied ready for direct use as a coating antigen on microplate wells for ELISA, or for resolving CMV structural proteins in Western Blot workflows. Researchers working on seroprevalence studies, transplant recipient screening, and congenital infection investigations rely on well-characterized CMV antigens to capture virus-specific antibodies in research samples and to confirm reactive results by immunoblot.

Because CMV (human herpesvirus 5) encodes numerous virion-associated proteins, the antigen preparation presents multiple immunodominant epitopes useful for detecting past exposure as well as active infection. The material is suitable for in-house assay validation, production of internal QC controls, and use as a positive control alongside clinical samples. For best stability, store frozen at -20 degrees C in single-use aliquots to limit freeze-thaw cycles, and dilute into coating buffer immediately before plate sensitization.
