Optimization of Dynamic Binding Capacity of Anion Exchange Chromatography Media for Recombinant Erythropoietin Purification
Background:The dynamic binding capacity (DBC) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. Optimization of the process criteria for maximum DBC avoids extra process scale-up and reduces ...
متن کاملPurification of DNA by anion-exchange chromatography.
Column chromatography has evolved to provide a rapid and effective alternative to more laborious methods for preparing high-quality DNA, such as CsCl-gradient centrifugation. This unit describes the use of a column made of a unique anion-exchange resin that selectively binds nucleic acids, allowing rapid separation of DNA from contaminating RNA, proteins, carbohydrates, and metabolites. The pro...
متن کاملCorrosion Behavior of Copper in Chloride Media
The electrochemical behavior of copper in 0.05 M HCl and 0.05 M NaCl carried out at open-circuit potential and at constant anodic potential after one hour has been investigated using electrochemical impedance spectroscopy (EIS) at 20 °C, 40 °C and 60 °C. The formation of copper chloride (CuCl) film does not protect copper from dissolution in the chloride media. The physical properties of the pa...

G . H evesy has written that [6] 1 " In view of the I.great similarity b etween hafnium and zirconium, i t ris hardly possible to separate these two elements in a lsingle operation ." A simple one-step separation c adequ a te for analytical work has still to be developed for hafnium-ziTconium mixtures, although recent work employing ion exchange has developed suitable methods for the separation...
