Preparation of ribosomal protein S14 polyclonal antibody in broiler pulmonary artery: Its application in broiler ascites syndrome.

RPS14 (ribosomal protein S14) gene maintains the normal physiological activities of the body by regulating the biosynthesis of ribosomes and the translation of important proteins. This study aims to explore the potential role of RPS14 in broiler ascites syndrome (BAS). We successfully prepared polyclonal antibody against RPS14 and studied the localization and expression of RPS14 protein in a variety of animal key tissues. In this experiment, the recombinant expression plasmid PET28a-RPS14 was constructed using the prokaryotic expression technology of foreign genes. Under the conditions of IPTG induction, a His-RPS14 protein with a molecular weight of about 22 kDa was expressed, and the purified recombinant protein was used as an antigen to prepare rabbit anti-chicken serum. Western blot results showed that the serum could specifically identify RPS14 protein in important tissues of broilers. Immunofluorescence combined with homology analysis showed that the antiserum had significant species specificity. Compared with other species, the expression of this protein in key tissues of broilers and ducks was more significant. More importantly, western blotting and immunofluorescence showed that BAS significantly reduced the expression level of RPS14. This further indicated that RPS14 protein can be used as one of the important entry points for BAS research. Copyright © 2021 Elsevier B.V. All rights reserved.
