Hi Lijun, once you solved and refined the structure, and you used for this the anisotropy truncated data, please PDB deposit both: manipulated data (the one you used for refinement the model), and the original dataset. This is very important. One day the software will be able to handle

Hi. We have been using His-Select Resin from Sigma in our lab for a number of years now. When we first bought the resin, I usually got much better purity of His tagged proteins compared with regular Ni-NTA resin. However, after regenerating the resin several times, the level of purity seems to

Hello Matthew, I almost always charge my IMAC resin with Co instead of Ni. I find that it gives much better purity because the selectivity is better. This is because the coordination sphere around the Co atoms require more His residues than the Ni coordination sphere. I believe Co requires 4

Hi, His-Select has been my favorite resin for IMAC for as long as Sigma's been selling it. It's not the cheapest resin but at roughly $11/ml packed bed volume and a capacity of ~10-20 mg protein per ml of resin bed (depends on protein size, quality, and other factors) there seems to be little
