An ELISA for antibodies to infectious bronchitis virus based on nucleocapsid protein produced in Escherichia coli
The nucleocapsid (N) gene of infectious bronchitis virus (IBV) strain X isolated in China was expressed in E. coli and was purified as a recombinant protein. An indirect ELISA assay (N-ELISA) for antibody detection was established using the purified recombinant nucleocapsid protein. Antigen coating conditions and serum dilution for the N-ELISA were optimized. The S/P ratio of the absorbency val...
متن کاملDevelopment of a recombinant protein-based dot-blot hybridization assay for the detection of antibody to chicken infectious bronchitis virus
Nucleocapsid (N) protein of infectious bronchitis virus (IBV), one of the viral structural proteins, inducesstrong antibody response in natural infection. In this study, a simple, recombinant N protein-based dot-blottest was developed to serologically examine chicken serum samples for the presence of IBV antibody.Initially, 72 serum samples were tested for the presence of IBV antibody using a c...
متن کاملMolecular Cloning and Expression of Nucleocapsid Gene of Chicken Infectious Bronchitis Virus Strain Massachusetts H120
Chicken infectious bronchitis virus (IBV) causes severe respiratory and renal dysfunction in chickens. In the present study, we used reverse transcription-polymerase chain reaction (RT-PCR) to amplify the nucleocapsid (N) protein gene of strain Massachusetts (Mass) H120 of IBV that is commonly used in the vaccine production in Iran. The PCR product with the expected size of 1.2 kb was cloned in...
متن کاملComparative anti-infectious bronchitis virus (IBV) activity of (-)-pinene: effect on nucleocapsid (N) protein.
In the present study, anti-IBV (infectious bronchitis virus) activities of (-)-pinenes were studied by MTT assay, as well as docking and molecular dynamic (MD) simulations. The CC₅₀ values of (-)-α-pinene and (-)-β-pinene were above 10 mM. And the maximum noncytotoxic concentrations (TD₀) of (-)-α-pinene and (-)-β-pinene were determined as 7.88 ± 0.06 and 6.09 ± 0.31 mM, respectively. The two c...
متن کاملCharacterization of the nuclear export signal in the coronavirus infectious bronchitis virus nucleocapsid protein.
The nucleocapsid (N) protein of infectious bronchitis virus (IBV) localizes to the cytoplasm and nucleolus and contains an eight-amino-acid nucleolar retention motif. In this study, a leucine-rich nuclear export signal (NES) (291-LQLDGLHL-298) present in the C-terminal region of the IBV N protein was analyzed by using alanine substitution and deletion mutagenesis to investigate the relative con...
