What is another word for affinity tag?
Pronunciation: [ɐfˈɪnɪti tˈaɡ] (IPA) 
Affinity tag is a term used in biotechnology to describe a molecule that is genetically fused to a protein of interest to facilitate its purification. There are several synonyms for this term, including epitope tag, fusion tag, and affinity marker. Epitope tag refers to a short amino acid sequence that is recognized by a specific antibody, often used for immunoprecipitation or immunoblotting. Fusion tag, on the other hand, simply refers to a protein or peptide sequence that is fused to the protein of interest to aid in purification. Affinity marker is also used to describe such a molecule, implying that it is used to specifically recognize and isolate a particular protein of interest. Regardless of the wording, affinity tags are an essential tool for protein purification and characterization in the biotechnology industry.
