A protein tag is a peptide sequence or carbohydrate which is genetically grafted onto a recombinant protein. The tag acts as an antigen that is recognized by an antibody. Tags fullfill various purposes when attached to proteins.
What are epitope tags?
Epitope tags are short peptide sequences which are chosen because high-affinity antibodies can be reliably produced in many different species. The technique of combining a recombinant protein with an epitope tag using genetic engineering is referred to as tagging. Epitope Tags are useful tools for the detection of proteins, especially when specific antibodies are lacking for example for newly discovered proteins and low abundant proteins. The sequence is often based on viral gene structures, which explains their high immunoreactivity.
