Dear everybody who reacted, It seems that when the His6 construct crystallizes, there is a fair chance that the his10 construct will crystallize as well. However, as usual in crystallography there is no guarantee, so I have added a TEV site to the construct in order to be able to remove the tag if necessary.

From literature, we know that the construct with a 6-histidine tag crystallizes. However, for other biophysical measurements, we would prefer to have a 10-histidine tag. Does anyone has experience with His-6 versus His-10 tags in terms of crystallization success? Thanks for your help! Herman
