Cloning and expression of Epstein-Barr viral antigens in Escherichia coli : purification of recombinant EBV antigens for diagnostic application
One of the factors associated with the etiology of nasopharyngeal carcinoma (NPC) is the Epstein-Barr virus (EBV). Ever since IgA antibodies towards the viral capsid antigen (VCA) and early antigen (EA) showed a high correlation with this disease, indirect immunofluorescence assays (IFAs) to detect...
