Affinity Processing of Cell-Containing Feeds Using monolithic Macroporous Hydrogels, Cryogels
关键词: affinity processing来源: 互联网
monolithic macroporous hydrogels, “cryogels,” are produced by polymerization in a partially frozen state when the ice crystals perform as a porogen. Cryogels have a unique combination of properties: (i) large (10–100 μm) pores; (ii) minimal non-specific interactions due to the hydrophilic nature of the polymers; (iii) porosities exceeding 80–90%; (iv) good mechanical stability. These properties of cryogels allow for their application for direct capture of extracellularly expressed histidine-tagged protein from the fermentation broth and separation of different cell types.
