Intended use of the test kit
This diagnostic test system for BLV infected cattle is intended to identify BLV p24 and gp51 antibodies in individual or pooled milk samples (≤ 10 samples). The sensitivity of the test is adjusted to the standards of the European Community with reference to the E4 serum and meets the requirements for testing milk samples in the European enzootic bovine leucosis (EBL) screening program. In contrast to test systems which make use of polyclonal antibodies or only one gp51 monoclonal antibody, this two monoclonal antibodies mediated ELISA gives a minimum of non-specific reactions.
Principle of the test kit
The test is based on the reaction of anti-BLV-p24 and anti-BLV-gp51 antibodies in test samples with BLV antigen.
The sample is added (diluted 1:1) to the wells of the coated plate.
After washing, milk samples are added to the wells and, if present, anti-BLV-p24 and anti-BLV-gp51 antibodies from the samples will bind to the antigen. The complex is detected by a horseradish peroxidase (HRPO) conjugated monoclonal antibody directed against bovine IgG.
Color reaction in the wells is directly related to the presence of BLV-p24 and BLV-gp51 antibodies in the sample.
