Aim:
To prepare the rabbit antibody against Dnop5 and identify its specificity.
Methods:
Dnop5 cDNA was amplified by RT-PCR, and then was subcloned into the fusion expression vectors pET28a(+). After being expressed in E.coli BL21, the truncated Dnop5 protein was purified and used to immunize rabbit. Purified antibody was obtained through affinity chromatography column with the expressed Dnop5. The specificity of the purified antibody was characterized by Western blot and immunohistochemical staining.
Results:
The Dnop5 gene was successfully inserted into pET28a(+). After induction, the fusion protein was expressed in the form of inclusion body. The purified fusion protein was obtained by affinity chromatography. After immunization of rabbits, the antibody against Dnop5 was obtained. Western blot analysis and immunohistochemical staining showed that the antibody had a good specificity.
Conclusion:
The rabbit antibody against Dnop5 has been successfully prepared, which lays the foundation for further study on the Dnop5 function.
