HisTrap FF Crude histidine-tagged protein purification columns, 5 x 5 ml
High binding capacity – binds up to 40 mg histag protein/mL resin.
Excellent flow properties – great performance even at high flow rates.
Optimized for unclarified samples – short purification time can minimize potential negative effects, such as degradation and oxidation of proteins.
HiTrap column format – compatible with syringe, pump, or chromatography system such as ÄKTA systems or other FPLC systems.
HisTrap FF crude is a readytouse column, prepacked with precharged Ni Sepharose 6 Fast Flow. This prepacked column is intended for purification of histidinetagged recombinant proteins by immobilized metal affinity chromatography (IMAC). After thorough cell disruption, it is possible to load the unclarified lysate on the column without precentrifugation and filtration of the sample. Extending the duration of the mechanical treatment of the sample to ensure a more complete lysis is recommended. For optimal results, we recommend first addition of lysozyme and DNase I followed by a mechanical lysis, for example by sonication. The homogenized sample can then be loaded directly on the column without a clarification step which may prevent degradation of the target protein and increase the activity.
Ni Sepharose 6 Fast Flow has low nickel ion (Ni2+) leakage and is compatible with a wide range of additives used in protein purification. The special design of the column in combination with the medium, provide fast, simple, and convenient purifications. Short purification time generally minimizes deleterious effects, such as degradation and oxidation of sensitive target proteins, and is therefore of great importance. HisTrap FF crude columns can be operated with a syringe, peristaltic pump, or liquid chromatography system such as ÄKTA design chromatography systems.
