Peptides of the capsid proteins vp1 or vp2 of the parvovirus b19

摘要

Immunologically active peptides or polypeptides with a partial amino acid sequence of the capside protein VP1 and VP2 of parvovirus B19 are obtained which provide an economical, sensitive and specific test to detect antibodies against the human parvovirus B19. Short peptide sequences are identified which when used as an antigen serve to identify anti-B19 IgG-positive sera. The production of these peptides by gene-technological means is revealed. Other gene-technologically produced antigens which form stably in large quantities in E. Coli and can subsequently be separated from them act as additional antigens for IgG confirmation. Finally a set of antigens facilitates testing for the detection of IgM antibodies against the virus. In addition, the gene-technologically produced components of the surface proteins are substances which may be used for prophylactic immunisation.
