Objective To prepare antibody against human S100A7(hS100A7).Methods The recombinant hS100A7 was prepared by prokaryotic expression and was used to immunize the rabbit.The titer and the specificity of the rabbit anti-hS100A7 antibody were analyzed by indirect ELISA and Western blot respectively.Results The recombinant hS100A7 and the antibody against hS100A7 was successfully prepared,the titer of the generated antibody was 1:16000 by ELISA.The results of Western blot and immunohistochemistry showed that this antibody not only could bind with recombinant hS100A7 but also native hS100A7 specifically.Conclusion The rabbit anti-hS100A7 antibody with high titer and high specificity has been prepared by using purified recombinant hS100A7 as immunogen.
