vakzinierende glycopeptide - antigen fraction with a large immunisierungsfaehigkeit, isolated from cultures of pathogenic germs, a process for isolating of this fraction and vaccines containing them

摘要

A glycopeptic vaccinating antigenic fraction with a very high level of immunogenicity, which is isolated from a culture of pathogenic germs comprises an osidic part present in a proportion of about 50%, with a proteinic part, which are linked together by covalent bond; when it is opposed to a suitable immune-serum, the fraction has an immunological image which essentially comprises a 'clear' line of precipitation close to the antigen pit, in immunodiffusion in gelose. The fraction is used for the preparation of vaccines and as a diagnostic agent.
