WebCleavage of your tag from your protein of interest. Some tags infer little risk to protein functionality but others, especially those of large size, can have downstream implications. In these cases, it is often desirable to cleave the tag from your protein of interest after the initial detection. 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.
