WebbThe His-tag is one of most ubiquitously used purification tags, and highly pure protein (more than 80%) can be obtained in a single chromatographic step from E. coli together with high expression. The FLAG tag (8 aa) [ 89 ] and Strep-II tag (8 aa) [ 90 ] are also small tags, but the purification costs may be higher compared with the His-tag. WebbWithin the realm of E. coli expression, the T7 system is the most popular approach for producing recombinant protein. In this system, the target gene is cloned into an expression vector downstream of the T7 promoter and this construct is …

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 commonly as His-Tag. The tag was invented by Roche, although the use of histidines an… WebbEscherichia coli strain 1100101 is a whole-genome sequenced bacterium that was isolated from a respiratory sample.
