The chromatography reagents market is categorized into gas chromatography, liquid and flash chromatography, thin layer chromatography, affinity chromatography, ion exchange chromatography, size exclusion chromatography, capillary electrophoresis and supercritical fluid chromatography, based on the technology.
Other systems are segmented into ion-exchange chromatography, affinity chromatography, supercritical fluid chromatography, column chromatography and thin layer chromatography.
Among the topics are ion exchange chromatography, affinity ligands from chemical and biological combinatorial libraries, membrane separations, conventional isoelectric focusing in gel slabs and capillaries and immobilized pH gradients, capillary electrophoretic separations, and high throughput screening techniques in protein purification.
This second edition reduces coverage of less-used techniques in favor of topics of greater current and future interest, such as expanded bed chromatography, affinity precipitation, immobilized metal affinity chromatography, and hydrophobic charge induction chromatography.
Several studies have demonstrated that the amount of glycohemoglobin measured by cation-exchange chromatography, affinity chromatography, and immunoturbidimetric assays equally well reflects the degree of glycemic control in diabetics.
