ABSTRACT
Objective:
To prepare a rabbit monoclonal antibody GCET2 and to investigate its diagnostic value in the workup of diffuse large B-cell lymphoma (DLBCL).Methods:
GCET2 rabbit monoclonal antibody was developed by using RabMAb® technology, and its specificity was confirmed by ELISA, Western blot, immunohistochemistry (IHC) and flow cytometry. A panel of immunomarkers including GCET2, CD10, bcl-6, MUM1, GCET1, FOXP1, Ki-67 and CMYC was evaluated in 81 cases of DLBCLs, 5 cases of follicular lymphomas (FL) and 2 cases of Burkitt's lymphomas.Results:
Rabbit monoclonal GCET2 antibody (clone EP316) was developed with specificity for normal germinal center B-cells (GCB) and GCB origined lymphomas. In 81 cases of DLBCL, the positive rate of GCET2 was 43.2%(35/81), which was significantly higher than that of other germinal center markers. Moreover, among 81 DLBCLs, the proportions of high CMYC expression in GCET2 negative and positive groups were 15.2% (7/46) and 2.8% (1/35), respectively.Conclusion:
GCET2 is a sensitive immunohistochemical marker for GCB derived lymphomas. Combined with other biomarkers, it may improve the diagnostic sensitivity of GCB-DLBCL.
