title: [Activity of the glycoprotein antigenic fractions of Mycoplasma pneumoniae in immunological reactions].
abstract: Glycoprotein fractions exhibiting pronounced antigenic properties in immunological in vitro reactions have been isolated from sonicated M. pneumoniae cells by extraction with glacial acetic acid and ethanol. Glycoprotein fraction 3 of M. pneumoniae antigen shows the highest blood-sensitive and precipitating activity and may be recommended as a diagnosticum for serological tests.
