A factor has been isolated from serum of homozygotes and obligate heterozygotes for cystic fibrosis using isoelectric focusing and disc electrophoresis as analytical methods. The factor is focused within an IgG-fraction with an isoelectric point of pH 8 to 9 but differs from IgG in its lower molecular weight. It is thus similar to, if not identical with,(More)
With one-dimensional electrophoresis or electrofocusing the selective demonstration of proteins and their genetically determined variants from complex compositions like the physiological body fluids often is possible only with specific staining techniques or immunofixation. By the method described here samples are separated by. PAG electrophoresis and a(More)
Fine and ultrafine Nd-Fe-B particles have been obtained from metallic cation reduction by borohydride ions both in water and microemulsions. In this way amorphous particles of different sizes ranging from 4-50 nm to 100-400 nm can be obtained. In this work we will report on the kinetics of the growth of the particles studied by stopped-flow with UV-Vis(More)
A pressure jump technique for fast kinetics using optical rotation and circular dichroism detection is presented and a suitable cell design for both detection methods is discussed. The detectability of changes in optical rotation far away from the Cotton region is considered, and measurements made on a pressure-dependent folding reaction of the protein(More)
Wouldn't the thought of a separate stump-cushioning, as mentioned by Heine, Eichler and others, make sense even today, regarding difficult and badly blood-supplied amputation-stumps? Shouldn't the thought of Hermann and Habermann, to do a knee-saving interference, be updated, especially for the weak and helpless patients? It is safe to say that one has to(More)
The association--dissociation kinetics of ribosomal particles from E. coli have been studied using a pressure-jump apparatus with optical detection. Experiments on isolated subunits yield two relaxation times of about 10 and 700 ms, respectively. With mixtures of 30 S and 50 S particles an additional relaxation time of about 100 ms is observed, which is(More)
