To prepare and identify monoclonal antibody (mAb) against human telomere-associated repression and activation protein 1 (Rap1).


BALB/c mice were immunized with recombinant Rap1 protein. The spleen cells of the immunized mice were fused with Sp2/0 cells. The positive clones were confirmed and selected by indirect ELISA for titer determination and specificity identification.


One hybridoma cell strain secreting specific mAb against Rap1 was obtained, namely 6F11. ELISA showed that the titer of the ascites was 1:10 000. Western blotting, immunoprecipitation and immunofluorescence experiments demonstrated that the mAb could specifically recognize and bind Rap1.


We have prepared mAb against human telomere-associated protein Rap1. The Rap1 mAb has a good binding ability and specificity.
