Analysis of Inorganic Polyphosphates by Capillary Gel Electrophoresis

Analysis of inorganic polyphosphates by capillary gel electrophoresis.

This paper describes the development of a method that uses capillary gel electrophoresis (CGE) to analyze mixtures of inorganic polyphosphate ((P(i))(n)). Resolution of (P(i))(n) on the basis of n, the number of residues of dehydrated phosphate, is accomplished by CGE using capillaries filled with solutions of poly(N,N-dimethylacrylamide) (PDMA) and indirect detection by the UV absorbance of a ...

Analysis of anion constituents of urine by inorganic capillary electrophoresis.

Inorganic capillary electrophoresis (ICE) is a new separations technology which melds the technique of classical electrophoresis with the separations approach of ion chromatography. Matrices which have been difficult to deal with using ion chromatography have proven amenable to analysis by ICE. The simultaneous analysis of weak acid anions, oxalate and citrate and inorganic anions, chloride, su...

Gel Electrophoresis in Capillary Electrophoresis

The discovery that antigen}antibody interaction could be produced not only in liquids, but also on gel media, such as agar or agarose gels, with the formation of insoluble immunoprecipitates, opened the door to the development of the gel diffusion techniques for immunoprecipitation analysis. The Rrst of these techniques, known as double diffusion, was introduced by Ouchterlony in 1948. In this ...

Purity and Content Analysis of Oligonucleotides by Capillary Gel Electrophoresis

Chromatography and electrophoresis are the most common techniques available for the separation of mixtures. For the analysis of large molecules, capillary gel electrophoresis (CGE) was not introduced until the late 1980s, well after most chromatographic techniques. Guttman et al.,1 Cohen et al.,2 and Kasper et al.,3 all independently, combined the principles of slab gel electrophoresis with the...
