Somatic antigens of Streptococcus group E. II. Separation and a partial physicochemical characterization.

Antigenic extracts of Streptococcus group E (SGE) were subjected to fractional ethanol precipitation, block (preparative) electrophoresis, and gel filtration for the purpose of separating the type antigen from the group antigen. Ethanol precipitation was ineffective in separating the substances. Block electrophoresis yielded serologically pure group antigen and a mixture of type and group antig...

DNA interference with radioimmunoassay procedures.

A bacterial factor preventing precipitation of immune complexes was purified from a culture of Streptococcus faecalis (AK strain) by gel filtration on Sephadex G-100 and Bio-Gel A-150m columns. The factor was identified as DNA on the basis of its ultraviolet absorption maximum at 260 nm, hydrolysis by deoxyribonuclease, Mr exceeding 1.5 X 10(8), and positive reaction with diphenylamine. DNA int...

تخلیص و ارزیابی آنتی ژنهای اصلی مایع هیداتیک در تشخیص ایمونولوژیک هیداتیدوز

    Regarding remarkable prevalence of human hydatidosis and despite introduction of novel sensitive techniques such as ELISA for immunodiagnosis of disease in the word, there has not been much progress in that field in Iran. Preparation and purification of suitable antigens is the basic and first step in serodiagnosis of this disease. The present study, thus, is designed and carried out for pr...

Membrane Adenosine Triphosphatase from Streptococcus faecalis

The membrane adenosine triphosphatase from SfrepfoCOCCUS faecalis has been purified by heat treatment, gel filtration through Agarose, and repeated chromatography on diethylaminoethyl cellulose. The purified ATPase appears to be homogeneous as judged from gel electrophoresis and sedimentation velocity studies. Sedimentation equilibrium studies, which are presented in the succeeding paper, also ...

Purification of a Streptococcal Bacteriocin ( Viridin B ) and Its Separation from Aipha - Hemolysin LYNN

Viridin B, a bacteriocin produced by Streptococcus mitis, copurified with the alpha-hemolysin after ammonium sulfate precipitation and gel filtration on Sephadex G-200. The bacteriocin and hemolysin were separated in some instances by ion-exchange chromatography on diethylaminoethyl-Sephadex A-50, but the two substances were shown to be distinct after polyacrylamide gel electrophoresis. Attempt...
