The latency.associated nuclear antigen (LANA) of Kaposi’s sarcoma- associated herpesvirus (KSHV) play. a key.role in the induction of cell transformation,maintenance of viral episome,and modulation of immune response in *** identify.the presence of B cell epitopes within C-terminus of LANA and to characterize the monoclonal antibodies (Mibs) against this protein,we expressed the C-terminal region at aa 794 -1000 of LANA (pLANA-C) in Escflerichia coli as a fusion protein. KSHV-positive human sera were able to recognize the recombinant LANA-C in the Western blot analy.is and *** of antigenic epitopes of pLANA-C by.KSHV-positive human sera revealed two B cell antigenic epitopes located at aa 846- 854 and aa 794 - *** mab 3Fll recognized a region between at aa 840 to 846 of LANA and exhibited a strong and specific binding to both pLANA-C and native viral *** findings showed that pLANA-C and mab 3F11 could be used for the detection of KSHV antibodies in human sera and for the advanced study.of biological functions of LANA.
