Recombinant porin OmpF (an integral protein of bacterial outer membrane) from Yersinia pseudotuberculosis was synthesized in Escherichia coli cells as inclusion bodies. By combining the methods of anion-exchange and gel filtration chromatographies, recombinant OmpF (rOmpF) was isolated as an individual protein in its denatured state, and its characteristic properties (molecular mass, N-terminal amino acid sequence, and hydrodynamic radius of the protein in 8 M urea solution) were determined. According to the data of gel filtration, dynamic light scattering, optical spectroscopy, and binding of the hydrophobic fluorescent probe 8-anilino-1-naphthalenesulfonic acid, the rOmpF is fully unfolded in 8 M urea and exists in random coil conformation ...

2:00 pm A PYRIDINE-BASED TRIDENTATE CHELATING SOLVENT EXTRACTION SYSTEM FOR SELECTIVE EXTRACTION OF NICKEL AND COBALT: Batric Pesic1, and Taili Zhou2, 1University of Idaho, College of Mines-McClure Hall, Moscow, ID 83843; 2The Shepherd Chemical Co., 4900 Beech St., Cincinnati, OH 45212. A novel pyridine-based tridentate chelating extractant, 2,6bis-[5-n-nonylpyrazo-3-yl] pyridine (BNPP), has been developed and characterized. The solvent extraction of Ni and Co by a mixed system of BNPP and dinonyl naphthalene sulfonic acid (DNNSA) was studied as a function of pH, diluent, temperature, and DNNSA concentration. Stripping of Ni and Co was examined as a function of HCl and H2SO4 concentration. The novel system can extract Ni and/or Co selectively against Fe, Mn, Ca, Mg, and Al from acidic sulfate solutions at a pH as low as 0.5. Separation of Ni and Co can be achieved either during loading, or during stripping stages of solvent extraction. The extractant system is stable and can be regenerated with ...

This work describes the fluorescence enhancement of the anilinonaphthalene sulfonate probes 1,8-ANS, 2,6-ANS, and 2,6-TNS via complexation with PAMAM dendrimer hosts of Generation 4, 5 and 6. The use of this set of three very closely related probes allows for comparative binding studies, with specific pairs of probes differing only in shape (1,8-ANS and 2,6-ANS), or in the presence of a methyl substituent (2,6-TNS vs. 2,6-ANS). The fluorescence of all three probes was significantly enhanced upon binding with PAMAM dendrimers, however in all cases except one, a very unusual spike was consistently observed in the host fluorescence titration plots (fluorescence enhancement vs. host concentration) at low dendrimer concentration. This unprecedented fluorescence titration curve shape makes fitting the data to a simple model such as 1:1 or 2:1 host: guest complexation very difficult; thus only qualitative comparisons of the relative binding of the three guests could be made based on host titrations.

EINECS (European INventory of Existing Commercial chemical Substances) as published in O.J. C 146A, 15.6.1990. EINECS is an inventory of substances that were deemed to be on the European Community market between 1 January 1971 and 18 September 1981. EINECS was drawn up by the European Commission in the application of Article 13 of Directive 67/548/EEC, as amended by Directive 79/831/EEC, and in accordance with the detailed provisions of Commission Decision 81/437/EEC.

There are various fluorescent probes such as ANS (anilinonapthalene 8-sulphonate) and N-methyl-2-anilino-6-naphthalene sulphonate (MNS). They both contain charged and hydrophobic areas and therefore are situated at the water-lipid interface of the membrane. The fluorescent properties of the molecule vary with its mobility and also with the polarity of the environment. Studies with the ANS probe has shown that structural changes occur in mitochondrial membrane during oxidative phosphorylation. These probes have also helped in giving information about the structural features of the plasma membrane. ...

Confluency and cell viability can be estimated with optical or fluorescence microscopy using appropriate dyes for cell staining (e.g. neutral red). Note that some hydrophobic dyes may adsorb onto the scaffold. Quantitative, colorimetric assays (see next section) are also compatible and can provide a more accurate measurement of cell numbers within a scaffold. We recommend recording a growth curve before using a new cell line in the Mimetix scaffold to get a feel for its growth behaviour in 3D and how long it takes for the cells to become half-confluent or confluent.. ...
