Epitope tag antibodies are highly specific monoclonal and polyclonal antibodies that provide a method to localize gene products in a variety of cell types. They are used to study the topology of proteins and protein complexes, identify associated proteins and characterize newly identified, low abundance proteins when specific antibodies are not available. Our epitope tag antibodies are conjugated with the most common dyes and enzymes used by researchers. We offer a wide selection of primary antibodies specific to epitope and affinity tags, fluorescent dyes, and fusion proteins. For popular targets, conjugates to biotin, HRP, and Alexa Fluor dyes are available.
Epitope tags are often genetically engineered into recombinant proteins during cloning, providing a method for the detection and/or purification of the expressed protein. Learn more about peptide tags, protein tags and fluorescent tags by downloading the epitope tags guide and table . Refer to the table for the most commonly used epitope tags.

Fluorescently conjugated lectins can be used in a similar manner as genetic tags, but for the identification and localization of glycoproteins in cells.
