The company Vitrotest produces the recombinant protein EBV VCA p18, which shows very good diagnostic characteristics, confirmed by its long-term use in ELISA kits as an antigen for sorption and in the form of a conjugate. The recombinant protein is an analog of capsid antigen p18 obtained in the E.coli expression system.
The range of Vitrotest products also includes the recombinant protein EBNA-1, which contains the immunodominant regions of the EBV nuclear antigen and is obtained in the E.coli expression system. The high quality of the protein is confirmed by its use as an antigen in ELISA kits.
