Selection of ligand peptides with the ability to detect antibodies in enzootic bovine leukosis

EM Dos Santos, R Cardoso, LRG Filho, MR Heinemann, RC Leite, JKP Dos Reis


Peptides present in phages were selected using phage display technology and immunoassays to find out the antigenic mimetics of immunodominant epitopes of bovine leukosis virus (BLV). The use of antigenic mimetics may result in the enhancement of the sensitivity and specificity of the serologic diagnosis of enzootic bovine leukosis (EBL), contributing directly to disease control. The selections enabled the choice of clones which can be used as potential antigens in the diagnoses of diseases. The synthetic peptide produced from the selected sequences may be considered as an alternative for antigens in the serologic diagnosis of enzootic bovine leukosis.

Key words: Diagnostic, antigens, enzootic bovine leukosis (EBL), phage display.
