Objective:
To obtain recombinant mouse collagenase ADAMTS2 (ADAM metallopeptidase with thrombospondin type 1 motif, 2) C terminal (1109-1213), and prepare the corresponding rabbit anti-ADAMTS2 polyclonal antibodies.
Methods:
The recombinant expression plasmid pGEX-6p-1-ADAMTS2 (1109-1213) was transformed into E.coli. The target protein was induced by IPTG and identified by mass spectrometry following affinity purification. The expressed and purified ADAMTS2 (1109-1213) protein was used to immunize New Zealand rabbits to prepare anti-ADAMTS2 polyclonal antibodies. The antibody titers were detected by ELISA and the antibody specificity by Western blotting.
Results:
The protein ADAMTS2 (1109-1213) was expressed in E.coli after IPTG induction, and with the purified protein, we prepared antiserum in the immunized rabbits. The titer of the antiserum reached over 1:160 000. The antiserum showed a good specificity.
Conclusion:
The high titer and specific rabbit anti-ADAMTS2 antibody has been prepared successfully.
