Abstract
E. coli strains have been created as producers of recombinant β1-adreno-receptor epitopes as part of chimeric proteins. The corresponding epitope sequences are located in the C-terminal region of the human heart fatty acid binding protein (hH-FABP) and separated from it by a linker sequence (Gly4Ser)3. A solid-phase enzyme-linked immunosorbent assay (ELISA) for detection of autoantibodies against β1-adrenergic receptor in human blood serum based on a recombinant epitope has been developed. Blood sera of patients (N = 76) with various diagnoses of cardiopathologies and other diseases were analyzed. In some patients with a con rmed diagnosis of cardiovascular diseases, a signi cantly increased level of autoantibodies to β1-adrenergic receptor was detected, in most cases those with a diagnosis of acute myocardial infarction.
