GE Healthcare has extended its line of HiScreen prepacked chromatography columns, bringing the total number of media available in that format to 23.
The four new offerings are: Ni Sepharose 6 Fast Flow columns for applications like purification of histidine-tagged recombinant proteins; Blue Sepharose 6 Fast Flow columns for binding proteins like albumin, interferon, and blood coagulation factors as well as kinases, dehydrogenases, and most enzymes requiring adenyl-containing cofactors; DEAE Sepharose Fast Flow columns for medium and weak anion exchange; and Butyl Sepharose High Performance columns for hydrophobic interaction chromatography.
Protein Discovery has released two new sample-preparation kits for mass spectrometry-based proteome research — the FASP Protein Digestion Kit and the FFPE-FASP Protein Digestion Kit.
The FASP kit enables the use of strong detergents in mass spec workflows, offering standardized sample prep for both soluble and insoluble proteins in fluids and tissues, the company said. The FFPE-FASP kit is designed to allow compatibility of formalin-fixed paraffin-embedded samples with downstream mass spec sample-prep techniques.
