Abstract

Abstract Glycoproteins obtained from the microbial bodies of at least one type selected from the group consisting of Pneumococci, Micrococci, Streptococci, Neisseria, Staphylococci, Klebsellia, Pneumoniae and Hemophilus influenzae, or from a mixture of at least two of the said strains, or an association of different types of the same microbial species, having a molecular weight of 1,000,000 or more, a content of combined hexoses between 60 and 65%, a content of protides of about 9%, a ratio of combined hexoses to protides of about 7, a molecular volume Ve/VO as determined through a gel of Sephadex G 200 of 1.0 to 1.2 in relation to a buffer having a pH value of 8, a content of Alpha -amine nitrogen between 1 and 2 %, and a migration by electrophoresis in density gradient comprised between Alpha proteins and Beta -proteins and their preparation.
