WebbThe result is expression of a recombinant protein with a 6xHis or poly-His-tag fused to its N- or C-terminus. Expressed His-tagged proteins can be purified and detected easily because the string of histidine residues binds to several types of immobilized metal ions, including nickel, cobalt and copper, under specific buffer conditions. In ...

A Histidine buffer can be used for anion exchange columns, having about the same buffer range as piperazine. However, the price might be considered a drawback, as well as the tendency of histidine to interact with metal ions.
WebbResults obtained from Henderson-Hasselbalch equation are approximate and only valid for diluted solutions (< 100mM) and in the pH range of pK a ± 1. pH value is a reverse function of temperature (pH decreases with increasing temperature and vice versa). pH value may change after dilution of concentrated buffer stocks. pH value may be affected by …
