These antibodies were evaluated by indirect immunoflourescence assay (IFA) and proved to react with the native FeLV antigen in agreement with the previous tests performed in animal samples. Considering its advantages to Brazilian scenario, the established IFA using recombinant antigen may be a practical and low cost diagnostic test to be incorpored as diagnosis of Feline Leukemia Virus.
