An Immunoblotting Procedure for Detection of Antibodies against Bovine Leukemia Virus in Cattle

Abstract
A sensitive protein immunoblotting (Western blot) procedure has been developed for detecting anti-BLV antibodies in cattle sera. The antibodies against most of the major viral proteins could be detected. This procedure does not give any non-specific background staining and there is absence of any erroneous results due to utilisation of purified viral preparations. The procedure has been applied for detection of antibodies to BLV in a set of 74 sera samples and it has been compared with other commonly used serological tests like ELISA and agar gel immunodiffusion test.
