Objective:
To establish the hybridoma cell lines secreting anti-ADAMTS13-T7 monoclonal antibodies (MA6) and to construct the MAb directed against different domains of ADAMTS13-T7.
Methods:
The trucated type protein ADAMTS13 of eukaryote-expressed recombinant ADAMTS13-T7 was constructed and was purified by using Ni-NTA agarose. Then the purified ADAMTS13 was used to immunize the BALB/c mice; the antiserum titer of ADAMTS13 protein of immunized mice was deteceted by ELISA. The spleen was taken from mice for construcing the single cell suspension, then the single cell suspension was mixed with myeloma cells SP2/0 at 10:1 ratio for cell fusion, and the elution culture of hybridoma cells was carried out; after 2 weeks, the wells in which clones were well grown were selected for detection, then the positive clonal wells were expansively cultured and the detection again was performed.
Results:
The purified ADAMTS13-T7 protein was gained. The ELISA showed that the antiserum titer in mice immumized by ADAMTS13-T7 protein was 1:20000. The results of fusion culture by hybridoma techmique showed that 30 hyridoma cell lines secreting MAb against recombinant ADAMTS13 were established.
Conclusion:
The hybridoma cell lines secreting MAb against recombinant ADAMTS13 have been successfully established by fusion culture, which provide more powerful tools for further screening the MAb with certain functional activity and studying the structure and function of ADAMTS13.
