The efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. Conclusions were drawn regarding selection of solid phase according to pore size, rigidity, pH stability, Chemistry of derivation and activation, and gross concentration of immobilized ligand require...

Propolis is a natural resin of a variety of plant origins collected by honeybees to seal gaps and cracks in their hives. Propolis was used as a remedy of various diseases due to its versatile biological activities. At least 200 compounds have been identified in the world. The present study aimed to investigate the chemical composition of two samples of Sudanese propolis collected from El-Faki H...

First part of review Micellar liquid chromatography is devoted to fundamentals and problems of retention modeling and optimization of separation. The 117 literature references have been critically analyzed. The known conceptual, mechanistic and empirical retention models are reviewed, classified and discussed. The methodologies of optimization of separation in high-performance liquid chromatogr...
