Analysis of Complex Bacterial Cell Division Proteins by Size Exclusion Chromatography (SEC)
By Umbreen Ahmed, Varian, Inc
Analysis of proteins by SEC is a powerful tool for investigating the structure and aggregation of proteins. By separating proteins on the basis of size in solution, SEC can be used to identify and isolate proteins from such complex systems. This application note demonstrates the analysis of FtsZ and ZipA, two essential cell division proteins involved in septum formation in Escherichia coli (E. coli). |

Flash Chromatography: Alumina for Normal Phase Separations
By Stephen Ball, Varian, Inc
Flash, a rapidly growing technique in the field of chromatography, is essentially a simplified, rapid form of preparative LC. It offers savings both in time and cost of materials when compared to traditional prep chromatography. This application note demonstrates the differences in chromatography obtained from silica and alumina flash cartridges of different types, using a 2-component mixture of fat-soluble vitamins. |
