Recombinant Protein: E. coli-Based Expression
A polyhistidine-tag is an amino acid motif in proteins that typically consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein. It is also known as hexa histidine-tag, 6xHis-tag, His6 tag, by the US trademarked name HIS TAG (US Trademark serial number 74242707), and most … See more In general, proteins possess more or less the ability to coordinate metal ions on their surface, and it is possible to separate proteins by chromatography making use of the difference in their affinity. This is the immobilized metal … See more The most common polyhistidine tags are formed of six histidine (6xHis tag) residues - which are added at the N-terminus preceded by Methionine or C-terminus before a stop … See more The polyhistidine-tag can be successfully used for the immobilization of proteins on a surface such as on a nickel- or cobalt-coated See more HQ tag The HQ tag has alternating histidine and glutamine (HQHQHQ). HN tag The HN tag has … See more Protein purification Polyhistidine-tags are often used for affinity purification of polyhistidine-tagged recombinant proteins expressed in Escherichia coli and other prokaryotic expression systems. Bacterial cells are harvested via See more The polyhistidine-tag can also be used to detect the protein via anti-polyhistidine-tag antibodies or alternatively by in-gel staining (SDS-PAGE) with fluorescent probes bearing metal ions. This can be useful in subcellular localization, ELISA, western blotting or … See more • Protein tag See more WebThe His tag is commonly expressed as a tag at the N- or C-terminal regions of recombinant protein. This allows isolation or purification by immobilized metal affinity chromatography. The affinity of the poly-histidine tag to Ni 2+ , by chelation, is strong and selective enough to enable purification of the protein by affinity chromatography on ... jared withers
