Abstract: This study was to investigate the changes of serum proteins in dairy cows immunized with Ure B subunit vaccine.Eight healthy cows were divided into 2 groups and immunized with 0.2 mg antigen protein or saline by intramuscular injection on both sides of the hip,once every two weeks,and total 4 times for immunization.Serum samples were collected on 56 d after immunization with Ure B subunit vaccine.Specific antibody in blood samples were determined by ELISA methods.Serum proteomic analysis were performed using two-dimensional gel electrophoresis(2-DE) coupled with MALDI-TOF-TOF mass spectrometer.Specific IgG were significantly higher after the cows immunized with Ure B subunit vaccine than control groups(P0.05),whereas IgM and IgA was not significant(P0.05).Proteomic analysis revealed 6 protein spots were differentially expressed,and 3 spots were successfully identified.Haptoglobin precursor and 3 unknown spots were up-regulated in cows immunized with Ure B subunit vaccine,while Kakapo was down-regulated.The current study showed that cows injection with Ure B subunit vaccine can result in the change of haptoglobin,Kakapo and other proteins,which provide the basis for further research of the physiology effects of Ure B subunit vaccine on dairy cows.
