A two-dimensional electrophoretic technique combining blue native polyacrylamide gel electrophoresis (BN-PAGE) with Tricine sodium dodecyl sulfate (SDS)-PAGE was previously used for the localization of oxidative phosphorylation (OXPHOS) defects in human diseases starting from biopsy or autopsy tissues (Schägger, H., Electrophoresis 1995, 16, 763-770). In the present work the technique was exten...

Pan 1 is an acidic outer membrane protein of Neisseria gonorrhoeae that is expressed only when gonococci are grown anaerobically. On silver-stained sodium dodecyl sulfate-polyacrylamide gels, Pan 1 migrates as an intense but diffuse 54-kDa protein. The deduced amino acid sequence of Pan 1 from the aniA (anaerobically induced protein) open reading frame reveals a lipoprotein consensus sequence, ...

Oat (Avena sativa cv Fulghum) fructan hydrolase was purified by ammonium sulfate precipitation and anion-exchange, hydrophobic interaction, and size-exclusion chromatography. The enzyme was purified to homogeneity as determined by the presence of a single band (43 kD) on a silver-stained sodium dodecyl sulfate-polyacrylamide gel. A mixture of /3-2,6-linked fructan (neokestin) isolated from oat ...

We report the purification to apparent homogeneity of an active opioid-binding protein solubilized from bovine striatal membranes. The purification was accomplished in two steps: affinity chromatography on beta-naltrexylethylenediamine (NED)-CH-Sepharose 4B followed by lectin affinity chromatography on wheat germ agglutinin-agarose. The ligand affinity-purified fraction exhibits stereospecific ...

The coordinative chemistry of the tridentate thiosemicarbazone ligand 2-pyridinecarboxaldehyde 4-N-ethylthiosemicarbazone (HL(Et)) has been explored by using an electrochemical methodology. All the complexes have been characterized using analytical and spectroscopic techniques. In the case of copper we have isolated two different complexes, with Cu(L(Et))(2).4H(2)O (6) and [Cu(2)(L(Et))(2)(SO(4...

The Pseudomonas aeruginosa polyvalent vaccine PEV and its 16 constituent monovalent extracts from International Antigenic Typing System serotypes 1 through 13 and 15 through 17 (J. J. Miler, J. F. Spilsbury, R. J. Jones, E. A. Roe, and E. J. L. Lowbury, J. Med. Microbiol. 10:19-27, 1977) were subjected to biochemical analysis and to detailed immunochemical analysis with rabbit anti-PEV immunogl...

Samples of articular cartilage of femur, tibia and patella of 15 dogs with experimentally induced degenerative joint disease (DJD) were microscopically analyzed. Animals were distributed into three groups (n=5): the control group received no medication; the second group was treated with chondroitin sulfate and the third received sodium hyaluronate. Samples were processed and stained with HE and...

Shyzophyllum commune IBL-06 produced 367 IU/mL of laccase in solid state bioprocess of banana stalk under optimum physical and nutritional parameters. The optimum SSF conditions were рH 4.5; temperature, 35°C; inoculum size, 3mL (10-10 mL); moisture content, 60%; C:N ratio in the medium, 15:1 (glucose and ammonium nitrate as additional carbon and nitrogen sources, respectively), ABTS (1mM), 1 m...

A silver staining method used routinely for detecting bacterial lipopolysaccharide (LPS) in sodium dodecyl sulfate-polyacrylamide gels (C. Tsai and E. Frasch, Anal. Biochem. 119:115-119, 1982) appeared to be inappropriate for visualizing certain LPS preparations. It did not stain S-form fractions of polyagglutinable Pseudomonas aeruginosa LPS or several partly deacylated (alkali-treated) S-form...

Today, one of the topical areas research is search for antiviral drugs to fi ght against virus-associated oncological manifestations. One viruses which a role in transformation cells proved Epstein-Barr virus (EBV), associated with variety lymphoproliferative diseases. The use that not only inhibit replication but also stimulate elimination tumor important treatment tumors viruses. purpose this...
