Comparison of the expression of NDV-F or AIV-NA in the presence or absence of pp38/pp24 dimers via IFA.

aThe intensity of protein expression is based on the detection rate of positive cells by flow cytometry. When the plasmids constructed by the bi-directional promoter transfect CEF, the molar ratio of different plasmids is basically the same, which could enter the cells to minimize the influence of transcriptional activity due to the different molar ratios, while there is no correlation between the molar ratio and transcription activity of bi-directional promoter transfecting CEF in two directions.
bND = not determined.
cIt is taken the ratio of positive cells appeared in the MDV-infected CEF which was transfected with the pPpp38-NA/1.8kb-F plasmid as 100%, and the data in the table was the relative expression intensity 48 hrs post different plasmids transfection.
