F1-protein-based indirect immunofluorescence kit for detecting type 4 fowl adenovirus antibody

The invention belongs to the field of biotechnology detection, in particular to an F1-protein-based indirect immunofluorescence kit for detecting a type 4 fowl adenovirus antibody. The kit comprises 293T cells expressing F1 protein, an FITC-labeled goat-anti-chicken antibody, a sample diluent and a washing liquid. The kit has good specificity and not only can be used for epidemiological investigation of serum type 4 fowl adenovirus infection conditions, but also can be used for monitoring the level of a serum type 4 fowl adenovirus antibody of immune chicken flocks and used for evaluating the immunoprotecive antibody level.
