THE SELECTION OF ANTIGENS FOR DETECTING OF IMMUNOGLOBULIN G TO CYTOMEGALOVIRUS ON THE BASIS OF FOSFAN TECHNOLOGY

The results of selection of composition of antigens to cytomegalovirus in the structure of multiplex test on the basis of FOSFAN™ technique are presented. In the process of detection of immunoglobulin G (IgG) to this virus the best indicators of sensitivity were registered with mosaic antigen containing immunodominant sequences of proteins pp150, gB, pp28 and pp52; reliably lower indicators of sensitivity was registered with phosphoprotein pp150; the lowest indicators of sensitivity were registered with proteins gB and pp65. The specificity made up from 93.5% to 96.8% independently of type of antigen. The mosaic antigen ensured the best ratio between sensitivity and specificity of immunoassay and is considered as the main component of immunochip for detecting IgG to cytomegalovirus.
