High Affinity Ni-Charged Resin FF

Description GenScript High Affinity Ni-Charged Resin FF is an 6% highly cross-linked agarose medium covalently coupled to a chelating agent that binds Ni2+ by four coordination sites for high-affinity purification of polyhistidine-tagged recombinant proteins (see Figure 1) [1]. High Affinity Ni-Charged Resin FF has low Ni2+ leakage, high protein-binding capacity and stability, and is compatible with a wide range of additives used in protein purification. This makes High Affinity Ni Charged Resin FF the excellent choice for high performance purification of polyhistidine-tagged proteins.

1 mM DTT6 M Gua·HCl
2% Triton X-1004 M MgCl250% glycerol
20 mM β-ME       
8 M Urea

10 mM reduced glutathione————100mM Na2SO460 mM citrate

Tested for 1 week at 40°C. 
The strong chelator EDTA has been used successfully in some cases at 1 mM. Generally, chelating agents should be used with caution (and only in the sample, not in buffers). Any metal ion stripping may be counteracted by addition of a small excess of MgCl2 before centrifugation/filtration of the sample. Note that stripping effects may vary with applied sample volume.
