Tag antibodies use short peptide sequences linked to their epitopes. Examples are V5-tag, Myc-tag, HA-tag and NE-tag. These tags are particularly useful for western blotting, immunofluorescence and immunoprecipitation experiments, although they also find use in antibody purification. Fluorescence tags (GFP) are used to give visual readout on a protein or as a folding reporter. Our customer support gladly helps you to find the antibody you need. All available epitope tags.
