Cytiva, 28992474, HiScreen Capto Blue

HiScreen columns are part of the process development platform available from Cytiva. The columns are prepacked with a range of BioProcess chromatography resins (resins) and designed for method optimization and parameter screening. HiScreen columns have small bed volumes (4.7 mL), reducing the cost of sample and buffer consumption. The resins used in HiScreen columns are also available in other prepacked formats and as bulk packs, for all scales of work from development and pilot studies to routine production. HiScreen Capto Blue is prepacked with the base matrix Capto to which Cibacron Blue 3G is covalently bound via a hydrophilic spacer immobilized with a stable amine bond. Capto Blue is highly chemically stable and has a more rigid agarose base matrix than Blue Sepharose 6 Fast Flow. This allows the use of faster flow rates and larger sample volumes, leading to higher throughput and improved process economy. The application area is the same as for Blue Sepharose Fast Flow (e.g., purification of albumin, enzymes including NAD+ and NADP+, coagulation factors, interferons, and related proteins). The main benefit of Capto Blue compared to Blue Sepharose 6 Fast Flow is its improved chemical stability provided with a new coupling chemistry involving a spacer arm. It tolerates repeated cleaning-in-place and sanitization at both high and low pH as well as autoclaving. Also the leakage of Cibacron Blue is reduced as compared to Blue Sepharose 6 Fast Flow.
