WebLimitations: Can have significant background binding in mammalian and insect cells. Overview. PolyHis tags are widely used for protein purification due to their small size and stable binding 1,2,3,4. Although tags can range from 2–10 histidine residues, the most common His-tag is the 6x-His tag, or hexatag, which contains six histidine residues. WebProtein binding capacity of resins is typically 10–40 mg/mL. Purity up to 95% can be achieved with optimized conditions. How does histidine-tagged protein purification work? Histidine-tagged proteins are commonly purified using Immobilized Metal Affinity Chromatography (IMAC). IMAC is based on the interaction between amino acid residues …

WebFeb 27, 2024 · In addition to these interactions, histidine can coordinate a wide variety of divalent transition metal ions (Zn, Ni, Cu, Fe, Co, Mn) via one or both of the deprotonated N atoms ( Figure 1 B) [ 27 ]. This is pH dependent since the nitrogen needs to be deprotonated (i.e., histidine is unable to bind metal under acidic conditions). WebHistidine-tagged protein kinase G [(His) 6-PknG] from Mycobacterium bovis was purified using a concentration of 45 mM imidazole in the sample and binding buffer.
