Preparations of E. coli 014 lipopolysaccharide (LPS) contain a common enterobacterial antigen (CA) in large amounts or in an immunogenic form. Chemical analysis revealed, in addition to o-acetyl groups, only those sugars which are present in the basal core structure of the E. coli or Salmonella LPS (e.g., galactose, glucose, glucosamine, heptose, and ketodeoxyoctonate). On treatment with acetic...
The enzyme disaggregatase (Dag) from Methanosarcina mazei was studied immunochemically. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of purified Dag under reducing and nonreducing conditions revealed a single band with a 94-kDa molecular mass. Dag was found to be immunogenic in rabbits; a polyclonal antibody probe was prepared and used to detect the enzyme by slide immunoenzymatic ...
We describe a new clinical laboratory instrument, the IMx, used to automate immunoassay testing in the clinical laboratory. The IMx incorporates a novel technology called Microparticle capture Enzyme ImmunoAssay (MEIA) for assays of high-molecular-mass analytes, and fluorescence polarization immunoassay (FPIA) for hapten assays. A front-surface fluorometer is used to quantify the enzymatic gene...
This review describes recent findings based on structural and immunochemical analyses of the cell wall mannan of Candida albicans, and other medically important Candida species. Mannan has been shown to consist of α-1,2-, α-1,3-, α-1,6-, and β-1,2-linked mannopyranose units with few phosphate groups. Each Candida species has a unique mannan structure biosynthesized by sequential collaboration b...
Estrada-Parra, Sergio (Escuela Nacional de Ciencias Biológicas, México, D.F., México), Abel Zamora, and L. F. Bojalil. Immunochemistry of the group-specific polysaccharide of Nocardia brasiliensis. J. Bacteriol. 90:571-574. 1965.-The group-specific polysaccharide of Nocardia brasiliensis was further purified, yielding an amorphous white material with the following characteristics: [alpha](D) (2...
