[Objective] This study aimed to prepare dairy cow anti-S100A12 antisera and develop a highly effective and sensitive immunological detection reagent for further investigation of the functions of dairy cow S100A12.[Method] Purified S100A12 protein was respectively emulsified with Freund’s complete adjuvant and Freund’s incomplete adjuvant as the antigen for immunizing New Zealand white rabbits to prepare the polyclonal antisera.The titer was detected using agar double diffusion assay and indirect enzyme-linked immunosorbent assay (ELISA) and the specificity was determined with Western Blot.[Result] The titer of anti-S100A12 antisera was 1∶8 as determined by agar double diffusion assay and over 1∶409 600 by ELISA.Western Blot result showed that the polyclonal antisera could be specifically combined with S100A12 protein.[Conclusion] The results indicated that anti-S100A12 polyclonal antibody with high titer and high specificity was successfully obtained, which provided a novel tool for further investigation of the functions of S100A12 gene.

[Method] Purified S100A12 protein was added emulsified with Freund’s complete adjuvant and Freund’s incomplete adjuvant as the antigen for immunizing New Zealand white rabbits to prepare the polyclonal antisera. The titer was detected using agar double diffusion assay and indirect enzyme-linked immunosorbent assay (ELISA) and the specificity was determined with Western Blot. [Result] The titer of anti-S100A12 antisera was 1:8 as determined by agar double diffusion assay and over 1:409 600 by ELISA. Western Blot showed showed the polyclonal antisera could be specifically combined with S100A12 protein. [Conclusion] The results indicated that anti- S100A12 polyclonal antibody with high titer and high specificity was successfully obtained, which provided a novel tool fo r further investigation of the functions of S100A12 gene.
