Ni Sepharose 6 Fast Flow is a high binding-capacity IMAC chromatography resin for purifying his-tagged proteins. Good choice for purification at a variety of scales. In process scale applications: This resin is used to purify histidine-tagged (his-tagged) and untagged recombinant proteins even at large scales. In research scale applications: This resin binds 40 mg his-tag protein/mL resin and is suitable for use in batch mode, with gravity flow, or when scalability is needed. Meets industrial demands with security of supply, robust performance, and regulatory support. Available as bulk resin and as prepacked columns for use with manual methods or a chromatography system. Excellent flow properties provide great performance even at high flow rates. High binding capacity resin with excellent flow propertiesNi Sepharose 6 Fast Flow (FF) is composed of cross-linked 6% agarose beads modified with a chelating ligand immobilized to the base matrix and precharged with nickel ions. The high dynamic binding capacity combined with the ability to withstand high flow rates gives an overall advantage of being able to increase flow rate and reduce the total time for protein purification considerably with a minimal loss in recovery. Therefore, this immobilized metal affinity chromatography (IMAC) purification resin is a good choice for scaling up.Successful use in research-scale applicationsLife science professionals use Ni Sepharose 6 Fast Flow for his-tag protein purification: Customer feedback on use in batch purificationIMAC chromatography of human β2-microglobulin in E. coli to 95% purityScale-up purification of a viral capsid protein from a prepacked columnCompatibile empty columns – research scaleCytiva offers a variety of empty columns for packing your own columns.
